Mutation analysis of a Chinese family with oculocutaneous albinism
Oculocutaneous albinism (OCA) is an autosomal recessive disorder characterized by either complete lack of or a reduction in melanin biosynthesis in the skin, hair, and eyes. OCA1, the most common and severe type, is caused by mutations in the tyrosinase (TYR) gene. In this study, we report a Chinese family with two members affected by OCA. Blood samples were collected from all family members. G...
متن کاملMutation analysis in a family with oculocutaneous albinism manifesting in the same generation of three branches.
PURPOSE To elucidate the molecular basis of oculocutaneous albinism with variable expressivity in a family from The Netherlands in which no consanguinity was reported. METHODS Three affected family members were screened for mutations in tyrosinase (TYR) and the pink-eye-dilution gene (P) by using SSCP. The melanocortin receptor gene (MC1R) and amplimers of P showing an aberrant banding patter...
متن کاملMutational analysis of a Chinese family with oculocutaneous albinism type 2
Oculocutaneous albinism (OCA) is an autosomal recessive disorder characterized by hypopigmentation of the skin, hair, and eyes accompanied with ophthalmologic abnormalities. Molecular genetic test can confirm the diagnosis of the four subtypes of OCA (OCA1-4). Herein, we report a Chinese family with two patients affected by OCA. Mutations of TYR, OCA2, TYRP1, and SLC45A2 were examined by using ...
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 Japanese Family With Autosomal Dominant Oculocutaneous Albinism Type 4.
Purpose We report the clinical characteristics of a Japanese family with autosomal dominant oculocutaneous albinism and a SLC45A2 gene mutation. Methods A total of 16 members of a Japanese family with general hypopigmentation and foveal hypoplasia underwent detailed clinical examinations. We evaluated the severity of foveal hypoplasia using spectral-domain optical coherence tomography (SD-OCT...
