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]

The c.413C>A (p.P138Q) alteration is located in exon 4 (coding exon 4) of the LGR6 gene. This alteration results from a C to A substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
