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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 17, 2024The c.736A>G (p.R246G) alteration is located in exon 5 (coding exon 4) of the MKX gene. This alteration results from a A to G substitution at nucleotide position 736, causing the arginine (R) at amino acid position 246 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
