Genes affected

EVX1 (HGNC:3506): (even-skipped homeobox 1) This gene encodes a member of the even-skipped homeobox family characterized by the presence of a homeodomain closely related to the Drosophila even-skipped (eve) segmentation gene of the pair-rule class. The encoded protein may play an important role as a transcriptional repressor during embryogenesis. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.187G>A (p.G63R) alteration is located in exon 1 (coding exon 1) of the EVX1 gene. This alteration results from a G to A substitution at nucleotide position 187, causing the glycine (G) at amino acid position 63 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
