Abstract
Okur-Chung syndrome is a neurodevelopmental condition attributed to germline CSNK2A1 pathogenic missense variants. We present 8 unreported subjects with the above syndrome, who have recognizable dysmorphism, varying degrees of developmental delay and multisystem involvement. Together with 6 previously reported cases, we present a case series of 7 female and 7 male subjects, highlighting the recognizable facial features of the syndrome (microcephaly, hypertelorism, epicanthic fold, ptosis, arched eyebrows, low set ears, ear fold abnormality, broad nasal bridge and round face) as well as frequently occurring clinical features including neurodevelopmental delay (93%), gastrointestinal (57%), musculoskeletal (57%) and immunological (43%) abnormalities. The variants reported in this study are evolutionary conserved and absent in the normal population. We observed that the CSNK2A1 gene is relatively intolerant to missense genetic changes, and most variants are within the protein kinase domain. All except 1 variant reported in this cohort are spatially located on the binding pocket of the holoenzyme. We further provide key recommendations on the management of Okur-Chung syndrome. To conclude, this is the second case series on Okur-Chung syndrome, and an in-depth review of the phenotypic features and genomic findings of the condition with suggestions on clinical management.

Abstract
Acrodermatitis enteropathica (AE) is a rare autosomal recessive disorder of zinc deficiency due to an abnormal intestinal zinc transporter. It is characterized by the triad of acral dermatitis, alopecia, and diarrhoea. Once AE is correctly diagnosed, patients are treated with orally administered zinc sulphate. In some patients, relapses occur during adolescence, despite the regular treatment. Here, we discuss the clinical and molecular features of a 13-year-old adolescent girl with acrodermatitis enteropathica who was resistant to high-dose zinc sulphate therapy. We successfully treated the patient with zinc gluconate and vitamin C, and we detected a novel homozygous c.541_551dup (p.Leu186fsX38) mutation in the exon 3 of her SLC39A4 gene.

Abstract
Background: Defective DNA repair has a causal role in hereditary colorectal cancer (CRC). Defects in the base excision repair gene MUTYH are responsible for MUTYH-associated polyposis and CRC predisposition as an autosomal recessive trait. Numerous reports have suggested MUTYH mono-allelic variants to be low penetrance risk alleles. We report a large collaborative meta-analysis to assess and refine CRC risk estimates associated with bi-allelic and mono-allelic MUTYH variants and investigate age and sex influence on risk. Methods: MUTYH genotype data were included from 20 565 cases and 15 524 controls. Three logistic regression models were tested: a crude model; adjusted for age and sex; adjusted for age, sex and study. Results: All three models produced very similar results. MUTYH bi-allelic carriers demonstrated a 28-fold increase in risk (95% confidence interval (CI): 6.95–115). Significant bi-allelic effects were also observed for G396D and Y179C/G396D compound heterozygotes and a marginal mono-allelic effect for variant Y179C (odds ratio (OR)=1.34; 95% CI: 1.00–1.80). A pooled meta-analysis of all published and unpublished datasets submitted showed bi-allelic effects for MUTYH, G396D and Y179C (OR=10.8, 95% CI: 5.02–23.2; OR=6.47, 95% CI: 2.33–18.0; OR=3.35, 95% CI: 1.14–9.89) and marginal mono-allelic effect for variants MUTYH (OR=1.16, 95% CI: 1.00–1.34) and Y179C alone (OR=1.34, 95% CI: 1.01–1.77). Conclusions: Overall, this large study refines estimates of disease risk associated with mono-allelic and bi-allelic MUTYH carriers.

Abstract
A 5-month-old female Great Dane puppy was treated for hematochezia, tenesmus, and rectal prolapse by resection of a 10-cm-long segment of colon and rectum. Grossly, the colorectal segment had diffuse mucosal and submucosal thickening with multiple polypoid nodules. The histologic diagnosis was colorectal hamartomatous polyps with ganglioneuromatosis. Duplication of PTEN was detected by quantitative multiplex polymerase chain reaction testing. The presence of 2 hamartomatous colorectal lesions with PTEN mutation is similar to human Cowden syndrome.

Abstract
OBJECTIVES We described epidemiological, clinical, histopathological and ultrastructural features of ichthyosis in the golden retriever breed in a prospective study. We also investigated the mode of transmission of this disease. MATERIALS AND METHODS We examined 150 golden retrievers, 73 of which were affected by ichthyosis (35 males and 38 females). We carried out detailed clinical and histopathological examinations for 40 affected dogs. Transmission electron microscopy was performed for two of them. We used pedigree analysis with the Cyrillic software to determine the mode of transmission. RESULTS Dermatological signs included a mild to moderate or severe generalised scaling with initially small to large whitish scales and progressively blackish scales. The ventral glabrous skin was hyperpigmented and rough, similar to sandpaper. Histopathological features were characterised by moderate to severe laminated or compact orthokeratotic epidermal hyperkeratosis without significant involvement of the stratum granulosum. Ultrastructural findings revealed laminated or compact keratin layers and numerous persistent corneodesmosomes within the stratum corneum. Analysis of the pedigree suggested an autosomal recessive inheritance. CONCLUSION The histopathological and ultrastructural characteristics strongly suggest that golden retriever ichthyosis is a retention ichthyosis, caused by absence of corneodesmosomal degradation, transmitted through an autosomal recessive mode.

Abstract
BACKGROUND Acrodermatitis enteropathica (AE) is an autosomal recessively inherited disease caused by a decreased intestinal zinc resorption and characterized by severe dermatitis (preferably hands, feet, mouth, genital region), chronic diarrhoea, retardation of growth and development, alopecia and increased proneness to infections. In 2002 it was shown that mutations in the zinc transporter gene SLC39A4 is the cause of AE. CASE REPORT Here we report 4 patients with typical clinical signs since early childhood. Under regular substitution with zinc all patients are more or less free of symptoms. The first patient revealed compound-heterozygous missense/nonsense mutations (P200L/ W401X), the three other patients were homozygous for a mutation in intron 1 (c.192 + 19G > A) of the SLC39A4 gene. CONCLUSION The diagnosis of hereditary acrodermatitis enteropathica can now easily be confirmed by mutation analysis of the SLC39A4 gene.

Abstract
The zinc transporter gene SLC30A4, located on chromosome 15q15-q21, has previously been reported to show altered expression patterns in post mortem analysis of the brains of schizophrenic patients. As a positional candidate we investigated SLC30A4 in the chromosome 15q15-linked schizophrenic phenotype periodic catatonia (MIM 605419), by means of a systematic mutation screening in affected individuals from exceptionally large pedigrees with perfect co-segregation of a chromosomal segment between marker D15S1042 and D15S659 in all affected individuals. The mutation scan revealed no genetic variants within the coding and the putative promoter region of SLC30A4 and, thus, excludes a genetic association of SLC30A4 with catatonic schizophrenia.

Abstract
Slc30a4 is the fourth and last identified member of a mammalian proteins family presumably involved in the cellular transport of zinc, solute carrier family 30. The murine homologue of the human SLC30A4 gene has previously been investigated and found responsible for the lm, a phenotype due to zinc deficiency. According to the strong homology between mouse and human SLC30A4 coding sequences, and to the very similar clinical features encountered in the murine lm and in human acrodermatitis enteropathica, SLC30A4 has appeared to us to be a good candidate for acrodermatitis enteropathica. Here we detail the genomic structure of human SLC30A4 together with its localization on chromosome 15q15-q21. We also report the mutational analysis of human SLC30A4 in ten families with acrodermatitis enteropathica, which enabled us to exclude this gene from any involvement in the disorder of the patients examined.
