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 16, 2024The c.262A>T (p.S88C) alteration is located in exon 2 (coding exon 2) of the LGR5 gene. This alteration results from a A to T substitution at nucleotide position 262, causing the serine (S) at amino acid position 88 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
