[Identification of a novel GPR143 mutation in a Chinese family affected with X-linked ocular albinism].

OBJECTIVE: To detect mutation of GPR143 gene in a Chinese patient affected with ocular albinism.

METHODS: Peripheral blood samples were collected from the proband and his parents. The coding regions of the GPR143 gene were subjected to PCR amplification and Sanger sequencing.

RESULTS: A previously unreported mutation (c.758T>A) was found in exon 6 of the GPR143 gene in the proband and his mother. The same mutation was not found in his father. As predicted, the mutation has resulted in a stop codon, causing premature termination of protein translation.

CONCLUSION: A novel mutation of the GPR143 gene related to X-linked ocular albinism has been identified.
