Mutational Analysis of the TYR and OCA2 Genes in Four Chinese Families with Oculocutaneous Albinism
BACKGROUND Oculocutaneous albinism (OCA) is an autosomal recessive disorder. The most common type OCA1 and OCA2 are caused by homozygous or compound heterozygous mutations in the tyrosinase gene (TYR) and OCA2 gene, respectively. OBJECTIVE The purpose of this study was to evaluate the molecular basis of oculocutaneous albinism in four Chinese families. PATIENTS AND METHODS Four non-consangu...
متن کاملGenetic analysis of oculocutaneous albinism type 1 (OCA1) in Indian families: two novel frameshift mutations in the TYR Gene.
PURPOSE Oculocutaneous albinism type 1 (OCA1) patients demonstrate a partial or total lack of melanin in the skin, hair and eye. OCA1 is an autosomal recessive genetic disorder caused by mutations in the TYR gene located at chromosome band 11q14-q25. The purpose of this study was to carry out genetic analysis of OCA1 in Indian families. METHODS Genomic DNA was isolated from blood leukocytes o...
متن کاملMutational Analysis of Oculocutaneous Albinism: A Compact Review
Oculocutaneous albinism (OCA) is an autosomal recessive disorder caused by either complete lack of or a reduction of melanin biosynthesis in the melanocytes. The OCA1A is the most severe type with a complete lack of melanin production throughout life, while the milder forms OCA1B, OCA2, OCA3, and OCA4 show some pigment accumulation over time. Mutations in TYR, OCA2, TYRP1, and SLC45A2 are mainl...
متن کاملOculocutaneous albinism
Oculocutaneous albinism (OCA) is a group of inherited disorders of melanin biosynthesis characterized by a generalized reduction in pigmentation of hair, skin and eyes. The prevalence of all forms of albinism varies considerably worldwide and has been estimated at approximately 1/17,000, suggesting that about 1 in 70 people carry a gene for OCA. The clinical spectrum of OCA ranges, with OCA1A b...
متن کاملa novel deletion mutation of the tyr gene in a patient with oculocutaneous albinism type 1a
introduction oculocutaneous albinism (oca) is a genetically heterogeneous autosomal recessive genetic disorder that is characterized by reduced or completely absent pigmentation in the hair, skin, and eyes. conclusions a novel homozygous mutation, the deletion of exons 1 - 5 on the tyr gene, was found on the molecular genetic testing of this patient. exon 1 - 5 deletion on tyr causes a lack of ...
