Bardet-Biedl syndrome (BBS, OMIM 209900) is a genetic disorder with the primary features of obesity, pigmentary retinopathy, polydactyly, renal malformations, mental retardation and hypogenitalism. Individuals with BBS are also at increased risk for diabetes mellitus, hypertension and congenital heart disease. What was once thought to be a homogeneous(More)
Bardet-Biedl syndrome (BBS) is a genetic disorder with the primary features of obesity, pigmentary retinopathy, polydactyly, renal malformations, mental retardation, and hypogenitalism. Patients with BBS are also at increased risk for diabetes mellitus, hypertension, and congenital heart disease. BBS is known to map to at least six loci: 11q13 (BBS1), 16q21(More)
Human MYO15A is located on chromosome 17p11.2, has 66 exons and encodes unconventional myosin XVA. Recessive mutations of MYO15A are associated with profound, nonsyndromic hearing loss DFNB3 in humans, and deafness and circling behavior in shaker 2 mice. In the inner ear, this motor protein is necessary for the development of hair cell stereocilia, which(More)
One t(14q14q), three t(15q15q), two t(21q21q), and two t(22q22q) nonmosaic, apparently balanced, de novo Robertsonian translocation cases were investigated with polymorphic markers to establish the origin of the translocated chromosomes. Four cases had results indicative of an isochromosome: one t(14q14q) case with mild mental retardation and maternal(More)
Distribution and prevalence of germline mutations in BRCA1 and BRCA2 differ among different populations. For the Turkish population, several studies have addressed high-risk breast cancer and ovarian cancer (BC-OC) patients. In most studies, both genes were analyzed in part, and a quite heterogeneous mutation spectrum was observed. For high-risk Turkish(More)
OBJECTIVES Retinoblastoma (RB1) gene involves in retinoblastoma, osteosarcoma, bladder, prostate, lung, breast carcinomas, and soft tissue sarcomas. Loss of heterozygosity (LOH) is the most common mutation of the gene. METHODS Xba I polymorphism in intron 17 of the gene was used to detect LOH in 20 bladder cancer patients. A cystitis and an osteosarcoma(More)
Primary tissue cultures of human lung tumors were prepared from 30 cases of which 16 were diagnosed as squamous cell carcinoma, six adenocarcinoma, four adenosquamous cell carcinoma, three large cell carcinoma, and one small cell lung carcinoma. Chromosomal abnormalities were observed in 26 cases by cytogenetic studies with a GTG banding technique. Specific(More)
We investigated 2604 marriages in Antalya, a region in the Mediterranean coast of Turkey. The 1020 urban and 1584 rural families included in the study were randomly selected and interviewed at their homes by one of the authors. The total consanguinity was 35.2%, rates being 39.6 and 28.3% for rural and urban areas, respectively. The frequency of(More)
Chromosomal anomalies may be a reason for male infertility. To find out whether this is true mitotic chromosome studies were performed on 41 males with azoospermia and 61 males with oligozoospermia. A constitutional chromosomal abnormality was diagnosed in 14 (34.1%) azoospermic patients and in 2 (3.3%) oligozoospermic patients. The 47,XXY karyotype was the(More)
To assess the trends in the frequency and the medical effects of consanguinity in the south coast of Turkish population using local and national data in the last 11 years. This cross-sectional study was carried out in Manavgat province, which is a major tourism center on the Mediterranean coast of Turkey. The authors studied consanguineous marriages in(More)
