ACSS2 gene variant associated with cleft lip and palate in two independent Hispanic populations.

Objectives/hypothesis: A candidate variant (p.Val496Ala) of the ACSS2 gene (T > C missense, rs59088485 variant at chr20: bp37 33509608) was previously found to consistently segregate with nonsyndromic cleft lip and/or palate (NSCLP) in three Honduran families. Objectives of this study were 1) to investigate the frequency of this ACSS2 variant in Honduran unrelated NSCLP patients and unrelated unaffected controls and 2) to investigate the frequency of this variant in Colombian unrelated affected NSCLP patients and unrelated unaffected controls.
