Abstract
PURPOSE Although multiple radiopharmaceuticals are currently available for sentinel node (SN) biopsy, 99mTc-tilmanocept is of particular interest due to its low molecular weight and specific binding capability for the mannose receptors of lymphatic reticuloendothelial cells. In the current systematic review and meta-analysis, we aimed to provide an update from a European expert panel on the performance of 99mTc-tilmanocept for SN biopsy. METHODS A systematic literature search of the PubMed/Medline and Embase databases was performed to identify studies on the use of 99mTc-tilmanocept for SN identification in oncological patients. The articles' methodological quality was assessed before inclusion. The pooled estimates of the pre-/intraoperative detection rates (DR; proportion of patients with ≥ 1 SN identified) and/or pN + sensitivity (SN + /pN + patients ratio), with 95% confidence intervals (CIs), were calculated for breast cancer, melanoma, and head and neck cancer. RESULTS Twenty-four articles were included in the systematic review, and twenty-one provided data for the meta-analysis. According to data availability, the 99mTc-tilmanocept-estimated pooled preoperative and intraoperative DRs were 0.94 (95%CI, 0.88-1.01) and 0.99 (0.98-1.00) for breast cancer, 0.98 (0.96-0.99) and 1.00 (0.99-1.00) for melanoma, and 0.97 (0.93-1.02) and 0.99 (0.96-1.01) for head and neck carcinoma. Finally, the pooled sensitivity for nodal metastasis in melanoma was 0.97 (95% CI, 0.92-1.03). CONCLUSION 99mTc-tilmanocept is a promising radiotracer for SN mapping in patients with breast cancer, melanoma, or head and neck cancer. We strongly believe that multicenter trials are still needed to assess if 99mTc-tilmanocept is superior to other radiotracers used in clinical routine.

Abstract
BACKGROUND Ultrarare Marshall-Smith and Malan syndromes, caused by changes of the gene nuclear factor I X (NFIX), are characterised by intellectual disability (ID) and behavioural problems, although questions remain. Here, development and behaviour are studied and compared in a cross-sectional study, and results are presented with genetic findings. METHODS Behavioural phenotypes are compared of eight individuals with Marshall-Smith syndrome (three male individuals) and seven with Malan syndrome (four male individuals). Long-term follow-up assessment of cognition and adaptive behaviour was possible in three individuals with Marshall-Smith syndrome. RESULTS Marshall-Smith syndrome individuals have more severe ID, less adaptive behaviour, more impaired speech and less reciprocal interaction compared with individuals with Malan syndrome. Sensory processing difficulties occur in both syndromes. Follow-up measurement of cognition and adaptive behaviour in Marshall-Smith syndrome shows different individual learning curves over time. CONCLUSIONS Results show significant between and within syndrome variability. Different NFIX variants underlie distinct clinical phenotypes leading to separate entities. Cognitive, adaptive and sensory impairments are common in both syndromes and increase the risk of challenging behaviour. This study highlights the value of considering behaviour within developmental and environmental context. To improve quality of life, adaptations to environment and treatment are suggested to create a better person-environment fit.

Abstract
BACKGROUND AND PURPOSE The aim of our study was to describe patients with the p.D12Y variant (previously reported as D11Y) in SOD1 showing heterogeneous clinicopathological features. METHODS We performed clinical, electrophysiological, magnetic resonance imaging (MRI) and muscle pathology studies in four SOD1 p.D12Y variant-positive patients. RESULTS The SOD1 p.D12Y clinical manifestations ranged from a benign phenotype characterized by distal distribution of muscular weakness and long survival to classic forms of amyotrophic lateral sclerosis with poor prognosis. Two patients with the distal clinical phenotype showed MRI and muscle pathology alterations indicating a concurrent muscle involvement. In one of these patients significant myopathic changes were associated with rimmed vacuolar pathology. CONCLUSIONS We expand the clinical spectrum of SOD1 p.D12Y variant, including predominant lower motor neuron forms with long survival and classic forms with aggressive course. Some patients may have concomitant distal myopathy without other explanations. Given clinical, MRI and muscle pathology alterations, SOD1 should be considered in the differential diagnosis of molecularly undefined distal myopathies with rimmed vacuoles.

Abstract
A case of acute monocytic leukemia with an apparent isolated skin relapse is reported. The cutaneous involvement was associated with a morphological bone marrow remission but a cytogenetic relapse was present. Regression of the skin lesions was obtained with a protocol including daunoblastine, aracytin and thioguanine, but the patient relapsed and died a few months later without achieving another remission. The relation between cutaneous and medullary disease is discussed.

Abstract
The clinical approach to patients with amyotrophic lateral sclerosis (ALS) has been largely modified by the identification of novel genes, the detection of gene mutations in apparently sporadic patients, and the discovery of the strict genetic and clinical relation between ALS and frontotemporal dementia (FTD). As a consequence, clinicians are increasingly facing the dilemma on how to handle genetic counselling and testing both for ALS patients and their relatives. On the basis of existing literature on genetics of ALS and of other late-onset life-threatening disorders, we propose clinical suggestions to enable neurologists to provide optimal clinical and genetic counselling to patients and families. Genetic testing should be offered to ALS patients who have a first-degree or second-degree relative with ALS, FTD or both, and should be discussed with, but not offered to, all other ALS patients, with special emphasis on its major uncertainties. Presently, genetic testing should not be proposed to asymptomatic at-risk subjects, unless they request it or are enrolled in research programmes. Genetic counselling in ALS should take into account the uncertainties about the pathogenicity and penetrance of some genetic mutations; the possible presence of mutations of different genes in the same individual; the poor genotypic/phenotypic correlation in most ALS genes; and the phenotypic pleiotropy of some genes. Though psychological, social and ethical implications of genetic testing are still relatively unexplored in ALS, we recommend multidisciplinary counselling that addresses all relevant issues, including disclosure of tests results to family members and the risk for genetic discrimination.

Abstract
We describe three sporadic ALS patients in which a D11Y SOD1 mutation was detected. All three patients disclosed a prolonged survival and a stereotypical distal limbs involvement in the initial stages of the disease. By this report we demonstrate that D11Y SOD1 mutation is associated with a peculiar phenotype and we confirm its probable pathogenetic role.

Abstract
Using array comparative genome hybridisation (CGH) 41 de novo reciprocal translocations and 18 de novo complex chromosome rearrangements (CCRs) were screened. All cases had been interpreted as "balanced" by conventional cytogenetics. In all, 27 cases of reciprocal translocations were detected in patients with an abnormal phenotype, and after array CGH analysis, 11 were found to be unbalanced. Thus 40% (11 of 27) of patients with a "chromosomal phenotype" and an apparently balanced translocation were in fact unbalanced, and 18% (5 of 27) of the reciprocal translocations were instead complex rearrangements with >3 breakpoints. Fourteen fetuses with de novo, apparently balanced translocations, all but two with normal ultrasound findings, were also analysed and all were found to be normal using array CGH. Thirteen CCRs were detected in patients with abnormal phenotypes, two in women who had experienced repeated spontaneous abortions and three in fetuses. Sixteen patients were found to have unbalanced mutations, with up to 4 deletions. These results suggest that genome-wide array CGH may be advisable in all carriers of "balanced" CCRs. The parental origin of the deletions was investigated in 5 reciprocal translocations and 11 CCRs; all were found to be paternal. Using customized platforms in seven cases of CCRs, the deletion breakpoints were narrowed down to regions of a few hundred base pairs in length. No susceptibility motifs were associated with the imbalances. These results show that the phenotypic abnormalities of apparently balanced de novo CCRs are mainly due to cryptic deletions and that spermatogenesis is more prone to generate multiple chaotic chromosome imbalances and reciprocal translocations than oogenesis.

Abstract
Megalencephaly (MEG), or enlargement of the brain, can either represent a familial variant with normal cerebral structure, or a rare brain malformation associated with developmental delay and neurological problems. MEG has been split into two subtypes: anatomical and metabolic. The latter features a build-up inside the cells owing to metabolic causes. Anatomical MEG has been detected in many different conditions, including many overgrowth syndromes. In 2004 Mirzaa et al. reported five non-consanguineous patients with a new MCA/MR syndrome characterized by severe congenital MEG with polymicrogyria (PMG), postaxial polydactyly (POLY) and hydrocephalus (HYD). The authors argued that these findings identified a new and distinct malformation syndrome, which they named MPPH. We report on a new case of MPPH, the first to be described after the original series (Mirzaa et al., 2004).

Abstract
Wolf-Hirschhorn syndrome (WHS) is a rare genetic disorder, which is caused by partial deletion of the short arm of one chromosome 4. Brain magnetic resonance (MR) imaging findings are lacking. We report on brain findings in 10 children with WHS. We evaluated the MR imaging films of 10 subjects affected by WHS, which had been confirmed by genetic study. The age range at MR imaging was between 1 month and 9 years. In 9/10 cases enlargement of the third lateral ventricles was present. In 9/10 cases a global reduction of cerebral hemispheres white matter was present. In 10/10 cases diffuse thinning of the corpus callosum was visible; it was severe in 7/10 cases. In 5/10 cases small foci of T (2) hyper intense signal were visible within the subcortical white matter. In three of the six cases studied within the first year of life frontal periventricular cysts were present. In three of the four cases studied after the first year of life a squared shape of the frontal horns of the lateral ventricles was visible. The MR imaging findings reported in WHS cannot be considered pathognomonic of the syndrome, however, they may suggest WHS.

Abstract
We report on the molecular cytogenetics studies in a healthy couple who had had three pregnancies which ended in a termination of pregnancy (TOP). In two of them, prenatal sonogram showed fetal dwarfism and in the third one, a chromosome alteration was found in the amniocentesis. A previous pregnancy ended in a healthy girl. A high-resolution G-band karyotype (550-850 bands), together with Fluorescence in situ Hybridization (FISH) techniques, detected in the father a 4p interstitial euchromatic duplication. This chromosome duplication appears to be a previously undescribed euchromatic variant (EV). We discuss the possibility that the 4p paternal EV could be involved in the clinical and genetic findings of the three TOPs.

Abstract
BRCA1 plays a pivotal role in the repair of DNA damage, especially following chemotherapy and ionising radiation. We were interested in the regulation of BRCA1 expression in acute myeloid leukaemia (AML), in particular in therapy-related forms (t-AML). Using real-time PCR and Western blot, we found that BRCA1 mRNA was expressed at barely detectable levels by normal peripheral blood granulocytes, monocytes and lymphocytes, whereas control BM-mononuclear cells and selected CD34+ progenitor cells displayed significantly higher BRCA1 expression (P=0.0003). Acute myeloid leukaemia samples showed heterogeneous BRCA1 mRNA levels, which were lower than those of normal bone marrows (P=0.0001). We found a high frequency of hypermethylation of the BRCA1 promoter region in AML (51/133 samples, 38%), in particular in patients with karyotypic aberrations (P=0.026), and in t-AML, as compared to de novo AML (76 vs 31%, P=0.0002). Examining eight primary tumour samples from hypermethylated t-AML patients, BRCA1 was hypermethylated in three of four breast cancer samples, whereas it was unmethylated in the other four tumours. BRCA1 hypermethylation correlated to reduced BRCA1 mRNA (P=0.0004), and to increased DNA methyltransferase DNMT3A (P=0.003) expression. Our data show that reduced BRCA1 expression owing to promoter hypermethylation is frequent in t-AML and that this could contribute to secondary leukaemogenesis.

Abstract
The authors report the unusual clinical and neurophysiologic features of a sporadic case of a boy carrying an 806delG mutation on the MECP2 gene. A 28-month-old boy was examined for severe developmental delay, seizures, microcephaly, breathing dysfunction, and spontaneous and evoked myoclonic jerks of upper limbs. Neurophysiologic study proved the cortical origin of myoclonus; however, it was not associated with signs of cortical hyperexcitability. 3-Methoxy-4-hydroxy-phenylethylene glycol and valine concentrations were low in CSF.

Abstract
Constitutional chromosome deletions can predispose to the development of cancer with the phenotypic characteristics of inherited cancer syndromes, when the deleted region encompasses a tumour suppressor gene. Examples of such conditions are represented by the cytogenetic deletions associated with retinoblastoma, Wilms tumour and familial adenomatous polyposis. So far, no constitutional deletions involving the genes implicated in hereditary non-polyposis colorectal cancer (HNPCC) have been identified. This may be at least partially because of the lack of distinctive phenotypic manifestations in HNPCC. We describe the first case of a constitutional microdeletion associated with HNPCC. Suspicion of a microdeletion was prompted by the association of mental retardation, postnatal growth deficiency, minor congenital anomalies and early onset (37 years) sporadic colon cancer. The patient was found to harbour a microdeletion within chromosome 2p16-p21, including the MSH2 gene. Since there are very few reports of deletions of the 2p16-p21 region, our observation sets the grounds for the definition of a novel multiple congenital anomaly/mental retardation/cancer microdeletion syndrome.

Abstract
Hypospadias, when the urethra opens on the ventral side of the penis, is a common malformation seen in about 3 per 1,000 male births. It is a complex disorder associated with genetic and environmental factors and can be part of genetic syndromes. Mowat-Wilson syndrome (MWS) is a multiple congenital anomaly syndrome characterized by a distinct facial phenotype, Hirschsprung disease, microcephaly and mental retardation. It is caused by mutations in the zinc finger homeo box 1B gene, ZFHX1B (SIP1). To date, 68 deletion/mutation-positive cases have been reported. Genitourinary anomalies are common in MWS. Here we report that hypospadias is common in males with this syndrome. In 39 patients where this information was available, hypospadias was present in 46% of patients (18/39). In the 3 Italian male cases reported here, hypospadias was always present. MWS should be considered by endocrinologists in patients with hypospadias associated with developmental delays/mental retardation, in particular in the presence of a distinct facial phenotype.

Abstract
We report on a boy with Pallister-Killian syndrome (PKS) who was conceived by assisted reproductive technology (ART), specifically in vitro fertilization (IVF) with parents' gametes. A prenatal diagnosis performed elsewhere by CVS failed to detect the presence of the isochromosome 12p that was demonstrated postnatally in approximately 50% of cultured skin fibroblasts. Given that the patient did not show the congenital overgrowth typical of PKS, we speculate that ART might have restricted overgrowth in this particular case. More broadly, we hypothesize that overgrowth might protect from early demise fetuses conceived by ART, a technology known to cause low and very low birth weight.

Abstract
Recent publications described two patients with a CFC-like phenotype and the same deletion of chromosome region 12q21.2q22 [Rauen et al., 2000, 2002]. The patients did not have the classical CFC phenotype and presented other signs not usually seen in CFC patients: the first patient had hydrocephalus, and the second, a history of olygohydramnios, normal stature, pyloric stenosis, cutaneous syndactyly of toes and bilateral transverse palmar creases. In order to verify if classic CFC patients with normal chromosomes in conventional preparations have microdeletions within the 12q21.2q22 chromosome region, we performed FISH analysis using 12 BAC probes to screen this area. The average interval between the probes was of approximately 1 Mb. No deletions were found in any of the 17 classical CFC patients we examined. We conclude that the region 12q21.2q22 is not a candidate region for CFC syndrome and that the patients described by Rauen et al. [2000, 2002] probably have a different condition, i.e., an aneuploidy syndrome, with some phenotypic resemblance to the CFC syndrome. To further evaluate the possibility of other chromosome imbalances, we performed a subtelomeric analysis, by FISH technique, of all chromosomes, and did not find any subtelomeric rearrangements.

Abstract
Cardiofaciocutaneous (CFC) syndrome is a multiple congenital anomalies/mental retardation syndrome characterized by congenital heart defects, characteristic facial appearance, short stature, ectodermal abnormalities and mental retardation. It was described in 1986, and to date is of unknown genetic etiology. All reported cases are sporadic, born to non-consanguineous parents and have apparently normal chromosomes. Noonan and Costello syndromes remain its main differential diagnosis. The recent finding of PTPN11 missense mutations in 45-50% of the Noonan patients studied with penetrance of almost 100% and the fact that in animals mutations of this gene cause defects of semilunar valvulogenesis, made PTPN11 mutation screening in CFC patients a matter of interest. We sequenced the entire coding region of the PTPN11 gene in ten well-characterised CFC patients and found no base changes. We also studied PTPN11 cDNA in our patients and demonstrated that there are no interstitial deletions either. The genetic cause of CFC syndrome remains unknown, and PTPN11 can be reasonably excluded as a candidate gene for the CFC syndrome, which we regard as molecular evidence that CFC and Noonan syndromes are distinct genetic entities.

Abstract
Prader-Willi syndrome is a genetic disease, which is clinically characterized by neonatal hypotonia, feeding problems in the first year of life, excessive eating with severe obesity from the second year of life, developmental delay, hypogonadism, typical facial features, short stature, behaviour problems, mental retardation. It is caused by a genomic imprinting disorder, i.e., lacking expression of paternally derived genes located on the long arm of chromosome 15. We present a case of a child with a neonatal diagnosis of Prader-Willi syndrome, founded on some facial dysmorphic features and a partial deletion of 15q, which we belied thanks to an anamnestic and clinical revaluation, and a metilation test. We also present main topics about Prader-Willi syndrome diagnosis, including clinical and endocrinological features, scoring system, and genetics.

Abstract
We report on a clinical-genetic study of 16 Wolf-Hirschhorn syndrome (WHS) patients. Hemizygosity of 4p16.3 was detected by conventional prometaphase chromosome analysis (11 patients) or by molecular probes on apparently normal chromosomes (4 patients). One patient had normal chromosomes without a detectable molecular deletion within the WHS "critical region." In each deleted patient, the deletion was demonstrated to be terminal by fluorescence in situ hybridization (FISH). The proximal breakpoint of the rearrangement was established by prometaphase chromosome analysis in cases with a visible deletion. It was within the 4p16.1 band in six patients, apparently coincident with the distal half of this band in five patients. The extent of each of the four submicroscopic deletions was established by FISH analyses with a set of overlapping cosmid clones spanning the 4p16.3 region. We found ample variations in both the size of the deletions and the position of the respective breakpoints. The precise definition of the cytogenetic defect permitted an analysis of the genotype-phenotype correlations in WHS, leading to the proposal of a set of minimal diagnostic criteria, which in turn may facilitate the selection of critical patients in the search for the gene(s) responsible for this disorder. We observed that genotype-phenotype correlations in WHS mostly depend on the size of the deletion, a deletion of <3.5 Mb resulting in a mild phenotype, in which malformations are absent. The absence of a detectable molecular deletion is still consistent with a WHS diagnosis. Based on these observations a "minimal" WHS phenotype was inferred, the clinical manifestations of which are restricted to the typical facial appearance, mild mental and growth retardation, and congenital hypotonia.

Abstract
A syndrome of mental retardation and multiple congenital anomalies, including craniosynostosis and overgrowth, was observed in two related individuals from a large kindred. Both of them carried a 15q25.1-qter trisomy associated with a subtle 13qter monosomy resulting from unbalanced segregation of a familial t(13;15)(q34;q25.1) translocation. Reportedly, a further individual in this kindred has the same condition. The present report confirms previous claims that gene(s) in the distal 15q region play a role in suture formation. At the same time it adds new data to the delineation of a 15q25-qter trisomy syndrome.

Abstract
Patients with the trisomy 9p syndrome and CNS abnormalities have been poorly assessed. We report a patient with trisomy 9p who showed band heterotopia on MRI. Abnormal neuronal migration is sufficiently frequent in patients with the trisomy 9p syndrome that brain MRI should be routinely considered in all patients with this syndrome.

Abstract
Chromosome imbalance affecting the short arm of chromosome 4 results in a variety of distinct clinical conditions. Most of them share a number of manifestations, such as mental retardation, microcephaly, pre- and post-natal growth retardation, anteverted and low-set ears, that can be considered as nonspecific signs, generally attributable to gene dosage impairment. On the other hand, more distinctive phenotypic traits correlate with the segmental aneuploidy. Duplications of the distal half of 4p give rise to the partial trisomy 4 syndrome, characterized by a "boxer" nose configuration and deep-set eyes. These signs are usually observed even in cases of small terminal duplications. Haploinsufficiency of 4p16.3 results in the so-called Wolf-Hirschhorn (WH) syndrome, a contiguous gene syndrome characterized by maxillary hypoplasia, large and protruding eyes, high nasal bridge, skeletal abnormalities, and midline defects. The smallest overlapping deletion described so far as a cause of this condition is only 165 kb long, suggesting that one or a few genes in this region act as "master" regulators of different developmental pathways. A "tandem" duplication of 4p16.1p16.3 was detected in association with a subtle deletion of 4p16.3pter on the same chromosome in a patient with the WH phenotype. The 3.2 Mb deletion, spanning the genomic region from the vicinity of D4S43 to the telomere, encompasses the recently delimited "WHS critical region" [Wright et al., 1997: Hum. Mol. Genet. 6:317-324]. This unusual chromosome rearrangement resulted in WH phenotype, clinical manifestations of partial 4p trisomy being mild or absent. This observation led us to speculate that the regulatory gene/genes in the critical WH region affect the expression of other genes in a dose-dependent manner. Haploinsufficiency of this region could be more deleterious than various partial trisomies.

Abstract
Leukemia has rarely been reported as a late complication of 131I therapy, occurring mostly after cumulative doses of 800 mCi. We observed two cases of acute myeloid leukemia (AML) after 131I therapy for hyperthyroidism and thyroid carcinoma, respectively. The first patient was a 45-year-old woman treated with a single dose of 27 mCi 131I for hyperthyroidism. She developed AML (FAB M2) 14 months after receiving 131I; the second patient was a 44-year-old man affected by refractory thyroid carcinoma who received a total dose of 1 Ci 131I plus radiotherapy and developed AML (FAB M6) 8 years after the first exposure to 131I. Although it is a very rare event, the occurrence of leukemia after 131I treatment should be kept in mind, considering the widespread use of 131I, particularly in the treatment of hyperthyroidism, and the unfavorable outcome of secondary leukemia.

Abstract
BACKGROUND With the exception of a single study the cytogenetic aspects of leukemic cells in the central nervous system (CNS) have not been investigated. PATIENTS AND RESULTS During the course of a work-in-progress on the chromosomal constitution both of the spinal fluid and of bone marrow (BM) in children with acute myeloblastic leukemia (AML), we have observed a unique case of AML and CNS leukemia (CNSL) at diagnosis. The patient showed the simultaneous presence at diagnosis of a 46 cytogenetic line in the spinal fluid and a 47 (+8) cell line in the BM, present in the great majority of the metaphases examined. DISCUSSION This observation allows hypotheses on the relationship between BM and CNS disease in AML. Regardless of the pathogenetic mechanism, the cytogenetic findings of the present case clearly suggest that the leukemic population in the CNS compartment represents a less malignant cell process compared to the BM leukemic population. This easily fits in with the usually less malignant course of CNSL in AML. CONCLUSION The foregoing findings may have critical pathogenetic and therapeutic implications.

Abstract
We describe two brothers, 11 and 13 years old, respectively, with an early-onset hereditary motor and sensory neuropathy, deafness, and mental retardation. Electrophysiological studies showed marked reduction of motor and sensory conduction velocity and absence of sensory action potentials. Sural nerve biopsy, performed in both patients, showed absence of large myelinated fibers with normal density of small myelinated fibers without axonal degeneration. Signs of demyelination were found only in the younger patient. We suggest that motorsensory neuropathy associated with deafness and mental retardation with absence of large myelinated fibers on sural nerve biopsy represents a distinct clinicopathological entity, which is transmitted in families probably as an autosomal recessive trait.

Abstract
Apparently normal chromosomes without a molecular 4p16.3 deletion were found in a patient with a Wolf-Hirschhorn syndrome (WHS) phenotype. During a 10-year-period of observation he consistently presented with typical facial appearance, moderate to severe mental retardation, normal physical development with normal head circumference. Genetic results and the relatively mild clinical manifestations suggest that a diagnosis of Pitt-Rogers-Danks syndrome (PRDS) may be more likely in this patient. If WHS and PRDS will ultimately prove to be caused by haploinsufficiency of the same gene in 4p16, non-deleted patients such as the present one will be good candidates for the search of point mutations in such putative gene.

Abstract
We report on a 15-year-old girl with a previously undescribed de novo duplication of segment 4q13.1-->q22.2. The origin of the extrachromosomal material on 4q was unequivocally established by fluorescent in situ hybridization with a chromosome 4 painting probe. Clinical manifestations included moderate mental retardation, destructive behavior, and minor physical anomalies. An analysis of the literature on partial 4q trisomy led us to identify a region comprising bands 4q22-q23, which may be involved in the development of the acrorenal field.
