Genes affected

HOXC13 (HGNC:5125): (homeobox C13) This gene belongs to the homeobox family of genes. The homeobox genes encode a highly conserved family of transcription factors that play an important role in morphogenesis in all multicellular organisms. Mammals possess four similar homeobox gene clusters, HOXA, HOXB, HOXC and HOXD, which are located on different chromosomes and consist of 9 to 11 genes arranged in tandem. This gene is one of several homeobox HOXC genes located in a cluster on chromosome 12. The product of this gene may play a role in the development of hair, nail, and filiform papilla.

Collection Method: clinical testing

The c.272C>T (p.A91V) alteration is located in exon 1 (coding exon 1) of the HOXC13 gene. This alteration results from a C to T substitution at nucleotide position 272, causing the alanine (A) at amino acid position 91 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
