Genes affected

HOXA13 (HGNC:5102): (homeobox A13) 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. Expansion of a polyalanine tract in the encoded protein can cause hand-foot-uterus syndrome, also known as hand-foot-genital syndrome. [provided by RefSeq, Jul 2008]

HOXA13 links:

HOTTIP (HGNC:37461): (HOXA distal transcript antisense RNA) This gene produces a long RNA in antisense to the HOXA gene cluster. This transcript may regulate expression of HOXA genes in cis. This gene is upregulated in tumors and is implicated in the promotion of cell proliferation. [provided by RefSeq, Dec 2017]

The missense c.884A>Cp.Gln295Pro variant in HOXA13 gene has not been reported previously as a pathogenic variant nor a benign variant, to our knowledge. The p.Gln295Pro variant has been reported with allele frequency of 0.006% in gnomAD Exomes and is novel not in any individuals in 1000 Genomes. This variant has not been reported to the ClinVar database. The amino acid change p.Gln295Pro in HOXA13 is predicted as conserved by GERP++ and PhyloP across 100 vertebrates. The amino acid Gln at position 295 is changed to a Pro changing protein sequence and it might alter its composition and physico-chemical properties. For these reasons, this variant has been classified as a Variant of Uncertain Significance VUS. -
