Genes affected

MKX (HGNC:23729): (mohawk homeobox) The protein encoded by this gene is an IRX family-related homeobox protein that may play a role in cell adhesion. Studies in mice suggest that this protein may be a regulator of tendon development. Two transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Jun 2011]

The c.539G>A (p.G180E) alteration is located in exon 5 (coding exon 4) of the MKX gene. This alteration results from a G to A substitution at nucleotide position 539, causing the glycine (G) at amino acid position 180 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
