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]

ACMG classification

Our verdict: Uncertain_significance. The variant received 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
