Abstract
Genetic cancer syndromes have identical clinical severity, limited therapeutic options, reduced life expectancy, and risks of genetic transmission, as do other genetic or congenital diseases for which prenatal genetic diagnosis or preimplantation genetic diagnosis (PGD) is allowed in the Netherlands. That was implied in the certification of one Dutch PGD centre at Maastricht University Hospital by the Dutch Ministry of Health, Welfare and Sport in 2003. A report by the Health Council of the Netherlands in 2006 confirmed this view with scientific and ethical evaluation. However, in 2006 the State Secretary for Health strongly objected to PGD for cancer, and disease risks of 50-100% for gene carriers, i.e. for highly, but not always fully penetrant genes. In 2006, the Maastricht centre discontinued PGD for cancer and couples were referred to other countries; prenatal genetic diagnosis remained available, however. On 26 May 2008, the present State Secretary proposed to parliament that the Health Council of the Netherlands report from 2006 be followed. This once again clashed with the fears of some Christian parties for a slippery slope and embryo selection for 'only a risk and not certainty of disease'. Yet no firm evidence for the existence of such a slope has been found. The Dutch framework for handling the ethical and medical evaluation of new reproductive and genetic technologies by the Health Council of the Netherlands Advisory Committees, professional and patient organisations, and the Ministry, has functioned for over 30 years without leading to any wrongdoing. There is no actual need for a new government body to license genetic tests on a case-by-case or per disease basis.

Abstract
BACKGROUND The present study aimed to assess predictors of distress after 'prophylactic mastectomy (PM) and salpingo-ovariectomy (PSO), in order to enable the early identification of patients who could benefit from psychological support. PATIENTS AND METHODS General distress and cancer-related distress were assessed in 82 women at increased risk of hereditary breast and/or ovarian cancer undergoing PM and/or PSO, before and 6 and 12 months after prophylactic surgery. Neurotic lability and coping were assessed before surgery. RESULTS Cancer-related distress and general distress at both follow-up moments were best explained by the level of cancer-related and general distress at baseline. Being a mutation carrier was predictive of increased cancer-related distress at 6-month follow-up (but not at 12 months), and of lower general distress 12 months after prophylactic surgery. Also, coping by having comforting thoughts was predictive of less cancer-related distress at 6-month follow-up. CONCLUSIONS Genetically predisposed women who are at risk of post-surgical distress can be identified using one or more of the predictors found in this study. Exploration of and/or attention to cancer-related distress and coping style before prophylactic surgery may help physicians and psychosocial workers to identify women who might benefit from additional post-surgical support.

Abstract
Frontotemporal dementia (FTD) is the second most prevalent dementia after Alzheimer's disease (AD). We compared 29 FTD and 90 AD caregivers with respect to burden, health-related quality of life (HQoL) and coping. FTD caregivers were more burdened than AD caregivers, and caregivers of patients who were demented for shorter duration had lower HQoL. We furthermore compared the 29 FTD caregivers with 34 caregivers of institutionalized FTD patients to understand their specific caregiver issues. Caregivers of FTD patients institutionalized after shorter dementia duration were most burdened and affected in their HQoL. Overall, passive coping strategies were associated with increased burden and decreased HQoL. We recommend that FTD caregivers be offered more support than AD caregivers. Furthermore, we suggest that interventions target passive coping strategies.

Abstract
The levels and course of psychological distress before and after prophylactic mastectomy (PM) and/or prophylactic salpingo-oophorectomy (PSO) were studied in a group of 78 women. General distress was measured through the hospital anxiety and depression scale (HADS), cancer-related distress using the impact of events scale (IES). Measurement moments were baseline (2-4 weeks prior to prophylactic surgery), and 6 and 12 months post-surgery. After PM, anxiety and cancer-related distress were significantly reduced, whereas no significant changes in distress scores were observed after PSO. At one year after prophylactic surgery, a substantial amount of women remained at clinically relevant increased levels of cancer-related distress and anxiety. We conclude that most women can undergo PM and/or PSO without developing major emotional distress. More research is needed to further define the characteristics of the women who continue to have clinically relevant increased scores after surgery, in order to offer them additional counselling.

Abstract
PURPOSE To assess the occurrence of high-risk epithelial lesions in women of breast cancer families with and without a BRCA mutation. PATIENTS AND METHODS Prospective study of women at very high risk of breast cancer undergoing prophylactic mastectomy (68 BRCA1 mutation carriers, 14 BRCA2 mutation carriers and 24 non-BRCA mutation carriers). RESULTS The prevalence of high-risk lesions is equal in women with a BRCA1 or a BRCA2 mutation, but is higher in non-BRCA mutation carriers: all lesions 43% versus 71% (p=0.02), atypical lobular hyperplasia 26% versus 67% (p=0.001), atypical ductal hyperplasia 17% versus 42% (p=0.01), lobular carcinoma-in situ 15% versus 29% (p=0.10) and ductal carcinoma-in situ 9% versus 17% (p=0.25). The presence of high-risk lesions is related to absence of a BRCA mutation and to age over 40 years. CONCLUSION Women with an autosomal dominant family history for breast cancer, with and without a BRCA mutation are prone to develop high-risk epithelial lesions, especially over 40 years.

Abstract
OBJECTIVE To discern behavioral problems that co-occur in frontotemporal dementia (FTD) patients, and to investigate the relation between behavioral clusters and the burden for caregivers. PATIENTS AND METHODS Baseline data of 63 FTD patients and their respective caregivers were used to detect the behavioral clusters in the Neuropsychiatric Inventory (NPI) and the accompanying distress evoked in caregivers. To detect the clusters in behavior of the FTD patients, we performed multidimensional scaling (procedure: PROXSCAL). Multiple regression analysis was used to determine the association between behavior of patients and the distress experienced by caregivers. RESULTS This was the first study that found behavioral clusters for FTD. Two behavioral clusters were found: agitation/psychosis (comprising delusions, hallucinations, irritability and agitation) and mood (made up of anxiety and depression). The remaining NPI domains (euphoria, disinhibition, aberrant motor behavior and apathy were found to be autonomous. After controlling for relevant confounding factors, caregiver distress was strongest related to agitation/psychosis, followed by mood. Disinhibition and aberrant motor behavior were mildly related to caregiver distress. Euphoria and apathy were not significantly related to distress. Caregivers of patients living at home were more distressed by the behavioral problems of the FTD patients than caregivers of hospitalized patients. DISCUSSION The high prevalence of psychopathology in FTD patients and the associated caregiver distress was confirmed in this study. Clustering behavioral symptoms allows investigation of the relationship between structural or functional cerebral deficits and neuropsychiatric symptoms.

Abstract
A family presented with three affected children with Leigh syndrome, a progressive neurodegenerative disorder. Analysis of the OXPHOS complexes in muscle of two affected patients showed an increase in activity of pyruvate dehydrogenase and a decrease of complex V activity. Mutation analysis revealed the T9176C mutation in the mtATPase 6 gene (OMIM 516060) and the mutation load was above 90% in the patients. Unaffected maternal relatives were tested for carrier-ship and one of them, with a mutation load of 55% in blood, was pregnant with her first child. The possibility of prenatal diagnosis was evaluated. The main problem was the lack of data on genotype-phenotype associations for the T9176C mutation and on variation of the mutation percentage in tissues and in time. Therefore, multiple tissues of affected and unaffected carriers were analysed. Eventually, prenatal diagnosis was offered with understanding by the couple that there could be considerable uncertainty in the interpretation of the results. Prenatal diagnosis was carried out twice on cultured and uncultured chorion villi and amniotic fluid cells. The result was a mutation percentage just below the assumed threshold of expression (90%). The couple decided to continue the pregnancy and an apparently healthy child was born with an as yet unclear prognosis. This is the first prenatal diagnosis for a carrier of the T9176C mutation. Prenatal diagnosis for this mutation is technically reliable, but the prognostic predictions are not straightforward.

Abstract
In 3 patients, 2 men aged 46 and 51 years and a woman aged 54 years, with colorectal cancer there was insufficient information on the basis of the family history to diagnose 'hereditary non-polyposis colorectal cancer' (HNPCC). Further investigation showed microsatellite instability in the tumour material, an indicator for a mutation in DNA-'mismatch repair' (MMR-) genes. Immunohistochemical study of lymphocytes showed an absence of the gene products MSH2 and MSH6. Study of the MMR genes revealed a pathogenic germ-line mutation in MSH2. All three patients were satisfied with genetic testing of the MMR-genes as this gave their children and their family members the opportunity to clarify genetic status. HNPCC is a clinical diagnosis, based on family history. As family history taking is often incomplete, the diagnosis is regularly not considered. The following individual criteria can help to recognize a patient at risk for HNPCC: (a) colorectal cancer diagnosed below 50 years of age, (b) second colorectal cancer, (c) a combination of colorectal and endometrial cancer.

Abstract
A family history of ovarian cancer without breast cancer can be a pitfall in interpreting the high breast cancer risks. A family with high breast and ovarian cancer risks due to a BRCA1 or BRCA2 mutation, can present itself with ovarian cancer only. In three women, 43, 50 and 61 years of age, there was a family history of ovarian cancer. In the youngest woman breast carcinoma was diagnosed and she was referred for genetic counseling and DNA mutation analysis. She was identified with a pathogenic mutation in BRCA1 and decided for regular breast examination and prophylactic adnectomy. The 50-year-old woman presented with ovarian cancer and was found to have a BRCA1 mutation. She received surgery and chemotherapy for her ovarian cancer and regular examination of the breasts. The third woman at risk could be reassured, since she did not carry the BRCA1 mutation that was found in her affected sister. Because the patients and their family members can benefit from regular surveillance and prophylactic surgery, it is of great importance to identify the high breast cancer risks as well as the high ovarian cancer risks in these families.

Abstract
The overall rate of an ipsilateral breast tumour recurrence (IBTR) after breast-conserving therapy (BCT) ranges from 1% to 2% per year. Risk factors include young age but data on the impact of BRCA1/2 mutations or a definite positive family history for breast cancer are scarce. We investigated IBTR after BCT in patients with hereditary breast cancer (HBC). Through our family cancer clinic we identified 87 HBC patients, including 26 BRCA1/2 carriers, who underwent BCT between 1980 and 1995 (cases). They were compared to 174 patients with sporadic breast cancer (controls) also treated with BCT, matched for age and year of diagnosis. Median follow up was 6.1 years for the cases and 6.0 years for controls. Patient and tumour characteristics were similar in both groups. An IBTR was observed in 19 (21.8%) hereditary and 21 (12.1%) sporadic patients. In the hereditary patients more recurrences occurred elsewhere in the breast (21% versus 9.5%), suggestive of new primaries. Overall, the actuarial IBTR rate was similar at 2 years, but higher in hereditary as compared to sporadic patients at 5 years (14% versus 7%) and at 10 years (30% versus 16%) (P=0.05). Post-relapse and overall survival was not different between hereditary and sporadic cases. Hereditary breast cancer was therefore associated with a higher frequency of early (2-5 years) and late (>5 years) local recurrences following BCT. These data suggest an indication for long-term follow up in HBC and should be taken into account when additional 'risk-reducing' surgery after primary BCT is eventually considered.

Abstract
The outcome of Down syndrome fetuses presenting with sonographic abnormalities in the second or third trimester is unclear. Therefore, we studied 55 pregnancies referred because of sonographically suspected fetal structural anomalies or growth retardation due to trisomy 21. A detailed ultrasound scan was performed in all cases to delineate the structural anomalies. Congenital heart malformations (CHMs) were diagnosed pre- and postnatally in 29 out of 55 Down fetuses (53%), with complete or incomplete atrioventricular septal defects (AVSDs) and ventricular septal defects (VSDs) being the most frequent anomalies. The most frequent noncardiac findings were a short femur (45%) and a small-for-gestational age (SGA) fetus (27%). Termination of pregnancy was carried out in 25 out of 55 pregnancies (45%). Of the 30 continued pregnancies, 10 ended with intrauterine death. The remaining 20 pregnancies resulted in the delivery of a live-born infant whose prognosis was poor, with a 1-year survival of only 60%. Combining intrauterine death and death in the first year indicated that the overall survival rate was only 40%. Fatal outcome was noted in 68% (13/19) in the presence of CHM, in 83% (10/12) in SGA fetuses, in 86% (6/7) in combined CHM and SGA, but only in 17% (1/6) in the absence of CHM and SGA. This study indictes that second- and third-trimester in utero diagnosis of Down syndrome has a poor outcome when associated with CHM and/or SGA. This is important in the genetic counseling of the parents.

Abstract
The group of acrofacial dysostosis (AFD) syndromes is very heterogeneous and contains many different entities. In 1990, Rodriguez et al. [1990: Am J Med Genet 35:484-489] described a new type of AFD characterized by severe mandibular hypoplasia, phocomelia and oligodactyly of the upper limbs, absence of fibulae, microtia, cleft palate, internal organ anomalies including arrhinencephaly and abnormal lung lobulation, and early lethality. We describe another case of AFD type Rodriguez, identified by prenatal ultrasonography at 25 weeks of gestation.

Abstract
OBJECTIVES To determine the effectiveness of early fetal anomaly scanning in a population at risk of fetal anomalies. DESIGN A prospective study in a tertiary center of 101 consecutive fetuses at risk of congenital anomalies at 11-14 weeks of gestation. RESULTS The principal (93/101 = 92%) reason for referral was having a previously affected infant. Nine (9/101 = 9%) fetuses were shown to have structural anomalies at the 11-14-week scan. In five of nine structurally affected fetuses, the nature of the anomalies was similar to that established in a previously affected pregnancy, four of which had a recurrence of an autosomal recessive syndrome. In two fetuses with a normal 11-14-week scan, anomalies were detected at the 18-21-week (arthrogryposis) or 30-week (cardiomyopathy) scans. CONCLUSIONS The majority of fetal anomalies can be diagnosed in the late first/early second trimesters of pregnancy. This will be of particular advantage to those women who are at high risk of having affected offspring. However, as fetal anomalies may present at varying gestational ages, the standard 18-21-week scan cannot be abandoned. The effectiveness of the early pregnancy scan depends on the natural history of anomalies (gestational age at onset) and the variable phenotypic expression of anomalies/syndromes.

Abstract
Androgen insensitivity is an X-linked disorder of male sexual differentiation resulting from a defective androgen receptor. Spinal and bulbar muscular atrophy (Kennedy's disease) is an X-linked disease, resulting from expansion of the polyglutamine stretch in the N-terminal part of the androgen receptor. Mutation analysis confirms the clinical diagnosis of androgen insensitivity and enables carrier detection and prenatal diagnosis. Kennedy's disease, with its diagnostic problem of clinical variability, is diagnosed or excluded when an expanded CAG-repeat is present or absent in exon 1 of the androgen receptor. Molecular testing can be used for carrier detection and genetic counselling.

Abstract
We report on a sibship with protein-losing enteropathy related to intestinal lymphangiectasia, a peculiar face, and genital anomalies. The parents are distantly related and from Dutch ancestry. The first patient was born with a protein-losing enteropathy, craniofacial anomalies, and renal defects. At 1 year of age, she died of severe complications of the protein-losing enteropathy and respiratory distress. Her brother was a cytogenetically normal male fetus identified by prenatal ultrasound at 19 weeks with similar anomalies. The pregnancy was terminated at 20 weeks. Autopsy showed müllerian duct remnants. These cases seem to confirm the Urioste syndrome [Urioste et al., 1993: Am J Med Genet 47:494-503]. Although it was previously only reported in 46,XY individuals, this report of a consanguineous family with an affected sibship of both sexes suggests it to be an autosomal recessive entity.

Abstract
In 517 Dutch families at a family cancer clinic, we screened for BRCA1/2 alterations using the Protein Truncation Test (PTT) covering approximately 60% of the coding sequences of both genes and direct testing for a number of previously identified Dutch recurrent mutations. In 119 (23%) of the 517 families, we detected a mutation in BRCA1 (n=98; 19%) or BRCA2 (n=21; 4%). BRCA1/2 mutations were found in 72 (52%) of 138 families with breast and ovarian cancer (HBOC), in 43 (13%) of the 339 families with breast cancer only (HBC), in 4 (36%) of 11 families with ovarian cancer only (HOC), and in nine of 29 families with one single young case (<40 years) of breast cancer. Between the different subgroups of families (subdivided by the number of patients, cancer phenotype and age of onset) the proportion of BRCA1/2 mutations detected, varied between 6 and 82%. Eight different mutations, each encountered in at least six distinct families, represented as much as 61% (73/119 families) of all mutations found. The original birthplaces of the ancestors of carriers of these eight recurrent mutations were traced. To estimate the relative contribution of two important regional recurrent mutations (BRCA1 founder mutation IVS12-1643del3835 and BRCA2 founder mutation 5579insA) to the overall occurrence of breast cancer, we performed a population-based study in two specific small regions. The two region-specific BRCA1 and BRCA2 founder mutations were detected in 2.8% (3/106) and 3.2% (3/93) of the unselected breast tumours, respectively. Of tumours diagnosed before the age of 50 years, 6.9% (3/43) and 6.6% (2/30) carried the region-specific founder mutation. Thus, large regional differences exist in the prevalence of certain specific BRCA1/BRCA2 founder mutations, even in very small areas concerning populations of approximately 200000 inhabitants.

Abstract
OBJECTIVE As metabolic and structural changes in frontotemporal-subcortical pathways have been reported in patients with obsessive-compulsive disorders, we investigated the correlation between complex compulsive behaviour (CCB) and the distribution of atrophy in a group of 90 patients with frontotemporal dementia (FTD). METHODS CCB was defined as complex, intentional, and time consuming repetitive behaviour, which was distinguished from simple compulsive behaviour (SCB), such as verbal and motor repetitions and utilisation behaviour. Cortical atrophy on CT and/or MRI was semi-quantitatively assessed in frontal, temporal, parietal and occipital regions, and the pattern of atrophy was compared between patients with and without CCB or SCB. Linear measures were used to establish the presence of caudate atrophy (bicaudate ratio) and ventricular enlargement (bifrontal ratio). RESULTS CCB was reported in 18 (21%) and SCB in 53 (61%) FTD patients. Frontotemporal atrophy was present in 64 patients (74%), and predominant temporal atrophy in 23 (26%). The pattern of atrophy was asymmetric in 25 patients (29%). Logistic regression analysis showed that temporal lobe atrophy (p < 0.005), as well as asymmetry of atrophy (p < 0.05) were independently associated with CCB, after adjusting for age at onset, gender, duration of symptoms at the time of imaging, severity of atrophy, and bicaudate and bifrontal ratio. No relationship was found between the presence of SCB and the distribution of atrophy, although patients with SCB tended to have more caudate atrophy (p < 0.1). CONCLUSION Temporal lobe atrophy appears to mediate CCB in patients with FTD, especially if asymmetry of atrophy is present. Future studies with quantitative and volumetric measurements of the cortical and subcortical structures may further clarify the aetiology of CCB in FTD.
