PG - 490-2 LID - 10.3760/cma.j.issn.1003-9406.2011.05.003 [doi] AB - OBJECTIVE: To determine the mutation responsible for the congenital fibrosis of the extraocular muscles type I(CFEOM1) in a Chinese family. METHODS: Direct sequencing of exons 20 and 21 in the KIF21A gene was performed for the proband. The mutation c.2860C to T in exon 21 was examined by allele specific-PCR (AS-PCR) analysis in other family members. Haplotype analysis was performed using four STR markers (D12S1668, D12S2194, D12S331 and D12S1048). RESULTS: A heterozygous mutation c.2860C to T in the KIF21A gene was identified in all three affected members with CFEOM1. Haplotype analysis suggested that the mutation might derive from maternal germline mosaicism. CONCLUSION: This Chinese family with CFEOM1 may be caused by a c.2860C to T mutation in the KIF21A gene.
