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 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.978

The c.332G>A (p.C111Y) alteration is located in exon 3 (coding exon 3) of the ADGRG6 gene. This alteration results from a G to A substitution at nucleotide position 332, causing the cysteine (C) at amino acid position 111 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
