▶Altered transmission of HOX and apoptotic SNPs identify a potential common pathway for clubfootAssociationN=1,927Audrey R. Ester et al.(2009)· American Journal of Medical Genetics Part A
Family-based association study identifying altered transmission of SNPs in HOX gene clusters (HOXA, HOXD) and IGFBP3 as potential risk factors for clubfoot (talipes equinovarus), a common congenital limb defect. Key findings include significant associations with rs3801776 in HOXA (p=0.004 discovery, p=0.028 validation), rs13223993 in IGFBP3 (p=0.003), and strong gene-gene interactions between HOX and apoptotic pathway genes (CASP3, CASP10, Bid, Apaf1), suggesting HOX and apoptotic perturbations affect limb and muscle development.
About HOXA9
In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development. This gene is part of the A cluster on chromosome 7 and encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. This gene is highly similar to the abdominal-B (Abd-B) gene of Drosophila. A specific translocation event which causes a fusion between this gene and the NUP98 gene has been associated with myeloid leukemogenesis. Read-through transcription exists between this gene and the upstream homeobox A10 (HOXA10) gene.[provided by RefSeq, Mar 2011]
