Genes affected

EVX2 (HGNC:3507): (even-skipped homeobox 2) This gene is located at the 5' end of the HOXD gene cluster on chromosome 2. The encoded protein is a homeobox transcription factor that is related to the protein encoded by the Drosophila even-skipped (eve) gene, a member of the pair-rule class of segmentation genes. A 117 kb microdeletion at the 5' end of the HOXD gene cluster, which includes this gene and the HOXD9-HOXD13 genes, causes synpolydactyly, a dominantly inherited disease resulting in limb malformation.

Collection Method: clinical testing

The c.1120G>A (p.A374T) alteration is located in exon 3 (coding exon 3) of the EVX2 gene. This alteration results from a G to A substitution at nucleotide position 1120, causing the alanine (A) at amino acid position 374 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
