Hearing loss is highly prevalent with a worldwide incidence of 1-2 per 1000 newborns. Several previous studies have demonstrated that mutations of connexin 26 (Cx26 or GJB2) are responsible for most cases of the recessive non-syndromic sensorineural hearing loss (NSSHL). Certain mutations have been described frequently among various populations, which(More)
Advances in understanding the genetic basis of renal disorders will soon allow for the clinical use of genetic diagnostic testing. In this article, we review renal diseases with a known genetic basis and the current methods available for genetic testing. We then examine the potential medical indications for genetic testing, with special attention to(More)
FLT3 mutations have been reported to be the most frequent mutation in acute myeloid leukemia (AML). No data currently exist regarding FLT3 mutations in Southeast Asian patients. In this study, the incidence and type of FLT3 mutation in a large series of Thai AML patients were determined. FLT3 internal tandem duplication (ITD) mutations were observed in(More)
ADAM33 (A Disintegrin And Metalloprotease 33) is an asthma susceptibility gene found across several human populations. However, no information on ADAM33 exists for Thai population. The objective of this study was to determine the association, if any, between ADAM33 polymorphisms and asthma in Thai subjects. Genotyping revealed 8 single nucleotide(More)
A cytogenetically visible interstitial deletion of chromosome band 10q23 was found in a 6-year-old boy with mental retardation, dysmorphic features, and juvenile polyposis coli. In order to map this patient's deletion physically, we performed fluorescence in situ hybridization by using yeast artificial chromosomes (YACs) in the vicinity of the deletion.(More)
We report on a 7-year-old boy with mosaic variegated aneuploidy (MVA) who developed embryonal rhabdomyosarcoma of the soft palate. This patient is the 11th case report of MVA and represents further documentation of the true existence of this rare mitotic mutant. Clinical findings share similarities to those previously described patients including(More)
We performed an observational prospective analysis to study the clinical characteristics as well as a molecular genetic analysis of 17 members of a Thai family who had visual loss and/or muscle weakness. Their blood mitochondrial DNA were examined for the presence of the G11778A Leber's hereditary optic neuropathy (LHON) mutation. Facioscapulohumeral(More)
Hereditary hemochromatosis is an iron overload disorder that can lead to the impairment of multiple organs and is caused by mutations in one or more different genes. Type 1 hemochromatosis is the most common form of the disease and results from mutations in the HFE gene. Juvenile hemochromatosis (JH) is the most severe form, usually caused by mutations in(More)
Liddle's syndrome is a rare form of autosomal dominant hypertension with early penetrance and cardiovascular sequelae. It is caused by missense or frameshift mutations in the epithelial sodium channel (ENaC) gene resulting in excessive salt and water resorption from the distal nephron, volume expansion, and suppression of plasma renin activity and serum(More)
