Abstract：
OBJECTIVE: To explore the genetic basis of a pedigree affected with oculodentodigital dysplasia.
METHODS: Genomic DNA was extracted from peripheral blood or amniotic fluid samples derived from the pedigree. Exon 2 of the GJA1 gene was amplified for sequencing.
RESULTS: Two pedigree members were found to carry heterozygous missense variation of the GJA1 gene, c.221A>C (p.H74P).
CONCLUSIONS: The missense c.221A>C variation of the GJA1 gene probably underlies the oculodentodigital dysplasia in this pedigree.
