Genes affected

DMXL1 (HGNC:2937): (Dmx like 1) The protein encoded by this gene is a member of the WD repeat superfamily of proteins, which have regulatory functions. This gene is expressed in many tissue types including several types of eye tissue, and it has been associated with ocular phenotypes. In addition, it is upregulated in cultured cells that overexpress growth factor independence 1B, a transcription factor that is essential for hematopoietic cell development. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.02 (15087/752968) while in subpopulation AMR AF= 0.0364 (787/21614). AF 95% confidence interval is 0.0343. There are 0 homozygotes in gnomad4_exome. There are 7946 alleles in male gnomad4_exome subpopulation. This position pass quality control queck.
