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]
EVX1-AS (HGNC:40223): (EVX1 antisense RNA) Predicted to enable chromatin binding activity. Predicted to be part of histone methyltransferase complex. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.589C>T (p.R197W) alteration is located in exon 2 (coding exon 2) of the EVX1 gene. This alteration results from a C to T substitution at nucleotide position 589, causing the arginine (R) at amino acid position 197 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
