Follow-up association studies of chromosome region 9q and nonsyndromic cleft lip/palate.

ABSTRACT: Cleft lip/palate comprises a large fraction of all human birth defects, and is notable for its significant lifelong morbidity and complex etiology. Several studies have shown that genetic factors appear to play a significant role in the etiology of cleft lip/palate. Human chromosomal region 9q21 has been suggested in previous reports to contain putative cleft loci. Moreover, a specific region (9q22.3-34.1) was suggested to present a approximately 45% probability of harboring a cleft susceptibility gene. Fine mapping of 50 SNPs across the 9q22.3-34.11 region was performed to test for association with cleft lip/palate in families from United States, Spain, Turkey, Guatemala, and China. We performed family-based analyses and found evidence of association of cleft lip/palate with STOM (rs30679
