Genes affected

ADGRG6 (HGNC:13841): (adhesion G protein-coupled receptor G6) This gene, which is upregulated in human umbilical vein endothelial cells, encodes a G protein-coupled receptor. Variations in this gene can affect a person's stature. Multiple transcript variants encoding different proteins have been found for this gene. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Likely_pathogenic. Variant got 8 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant located near the start codon (<100nt), not predicted to undergo nonsense mediated mRNA decay. Fraction of 0.995 CDS is truncated, and there are 3 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 6-142309560-C-T is Pathogenic according to our data. Variant chr6-142309560-C-T is described in ClinVar as [Pathogenic]. Clinvar id is 192347.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr6-142309560-C-T is described in Lovd as [Pathogenic].
