Genes affected

IRX3 (HGNC:14360): (iroquois homeobox 3) IRX3 is a member of the Iroquois homeobox gene family (see IRX1; MIM 606197) and plays a role in an early step of neural development (Bellefroid et al., 1998 [PubMed 9427753]). Members of this family appear to play multiple roles during pattern formation of vertebrate embryos (Lewis et al., 1999 [PubMed 10370142]).[supplied by OMIM, Aug 2009]

Ambry Genetics

Feb 28, 2024

The c.1016C>A (p.A339D) alteration is located in exon 2 (coding exon 2) of the IRX3 gene. This alteration results from a C to A substitution at nucleotide position 1016, causing the alanine (A) at amino acid position 339 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
