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

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.1558455).

BS1

Variant frequency is greater than expected in population nfe. gnomad4_exome allele frequency = 0.0000281 (41/1457704) while in subpopulation NFE AF= 0.0000342 (38/1109816). AF 95% confidence interval is 0.0000254. There are 0 homozygotes in gnomad4_exome. There are 12 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Collection Method: clinical testing

The c.34C>T (p.H12Y) alteration is located in exon 2 (coding exon 2) of the ADGRG6 gene. This alteration results from a C to T substitution at nucleotide position 34, causing the histidine (H) at amino acid position 12 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
