Genes affected
LGR5 (HGNC:4504): (leucine rich repeat containing G protein-coupled receptor 5) The protein encoded by this gene is a leucine-rich repeat-containing receptor (LGR) and member of the G protein-coupled, 7-transmembrane receptor (GPCR) superfamily. The encoded protein is a receptor for R-spondins and is involved in the canonical Wnt signaling pathway. This protein plays a role in the formation and maintenance of adult intestinal stem cells during postembryonic development. Several transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 02, 2024The c.257T>G (p.L86R) alteration is located in exon 2 (coding exon 2) of the LGR5 gene. This alteration results from a T to G substitution at nucleotide position 257, causing the leucine (L) at amino acid position 86 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
