Genes affected

GOSR2 (HGNC:4431): (golgi SNAP receptor complex member 2) This gene encodes a trafficking membrane protein which transports proteins among the medial- and trans-Golgi compartments. Due to its chromosomal location and trafficking function, this gene may be involved in familial essential hypertension. [provided by RefSeq, Mar 2016]

ENSG00000262633 (HGNC:):

LRRC37A2 (HGNC:32404): (leucine rich repeat containing 37 member A2) Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

GOSR2-DT (HGNC:55346): (GOSR2 divergent transcript)

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, 0.961
