Genes affected

LGR6 (HGNC:19719): (leucine rich repeat containing G protein-coupled receptor 6) This gene encodes a member of the leucine-rich repeat-containing subgroup of the G protein-coupled 7-transmembrane protein superfamily. The encoded protein is a glycoprotein hormone receptor with a large N-terminal extracellular domain that contains leucine-rich repeats important for the formation of a horseshoe-shaped interaction motif for ligand binding. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP3

Multiple lines of computational evidence support a deleterious effect 6: BayesDel_noAF, Cadd, Dann, Eigen, FATHMM_MKL, PROVEAN [when max_spliceai, MetaRNN, MutationTaster, phyloP100way_vertebrate was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.2695044).

The c.493C>T (p.R165C) alteration is located in exon 5 (coding exon 5) of the LGR6 gene. This alteration results from a C to T substitution at nucleotide position 493, causing the arginine (R) at amino acid position 165 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
