Genes affected

GPR179 (HGNC:31371): (G protein-coupled receptor 179) This gene encodes a member of the glutamate receptor subfamily of G protein-coupled receptors. The encoded protein has an EGF-like calcium binding domain and a seven transmembrane domain in the N-terminal region of the protein. Mutations in this gene are associated with congenital stationary night blindness type 1E. [provided by RefSeq, Apr 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 5 ACMG points.

• PS1: Transcript NM_001004334.4 (GPR179) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 17-38334016-G-A is Pathogenic according to our data. Variant chr17-38334016-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 31200.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr17-38334016-G-A is described in Lovd as [Pathogenic].
