Major neurological disorders may accompany rare chromosomal abnormalities. As an example of this rare condition, we present a case with microcephaly, mental retardation, developmental delay, hyperactivity, stereotypic movements, seizures and dysmorphic facial appearance in whom a mosaic ring chromosome 18 was found [45,XX,-18/46,XX,r(18)/46,XX,dicr(18)].(More)
Obesity is a multifactorial disease that is influenced by genetic and environmental factors. The apolipoprotein E (Apo E) polymorphism has been reported to influence some lipid profile abnormalities associated with obesity in childhood. In this study, the relationship between the Apo E gene and Taq1A polymorphisms with childhood obesity has been studied.(More)
Two common forms of autoimmune thyroid diseases are Graves' disease and Hashimoto's thyroiditis. Cytotoxic T lymphocyte antigen 4 (CTLA4) encoded by the CTLA4 gene on chromosome 2q33 plays a role in susceptibility to Graves' disease and is probably important also for Hashimoto's thyroiditis as well as for the other endocrine autoimmune disorders. The CTLA4(More)
Supernumerary marker chromosome 15 (sSMC[15]) is the most frequent marker chromosome, and it is generally regarded as unimportant if it does not contain the Prader-Willi/Angelman syndrome critical region (PWACR). The clinical importance of the larger markers in association with the critical region is mentioned in almost all reports related to marker(More)
Reported here is a 2-year-old girl who was diagnosed to have thiamine-responsive megaloblastic anemia during evaluations for her bilateral neurosensorial deafness. Besides reporting a new mutation on the gene SLC19A2 for the first time in the literature, we highlight the recognition of this syndrome--when megaloblastic anemia and diabetes mellitus(More)
Ring chromosome 22, a rare cytogenetic finding, was first described in 1968, and since then about 60 patients have been reported. We describe a new patient with ring chromosome 22 syndrome and discuss the common features of the previously reported cases. Our patient had the major features of this syndrome including mental retardation, hypotonia, motor(More)
Congenital radio-ulnar synostosis may be an isolated abnormality or additional abnormalities may accompany it. It may also be found as a part of well-known syndromes. We present a case with bilateral congenital radio-ulnar synostosis, speech delay, dimple on shoulders, café au lait spot and characteristic facial appearance. The proband has a brother with(More)
Abstract Objective. The aim of this study is to contribute to the understanding of schizophrenia genetics by using efficient algorithmic examination techniques including dysmorphic examination, karyotyping, and Fluoresence in situ hybridization (FISH). Methods. In this study we have investigated 20 familial schizophrenia patients from Turkey who had an(More)
Hairy Elbows Syndrome (Hypertrichosis Cubiti; OMIM# 139600) is a rare syndrome, and characterized by the presence of long vellus hair localized on the extensor surfaces of the distal third of the arms and proximal third of the forearm bilaterally. Occasionally hypertrichosis of other body regions may accompany hairy elbows. About half of the reported(More)
