Genes affected

MLNR (HGNC:4495): (motilin receptor) Motilin is a 22 amino acid peptide hormone expressed throughout the gastrointestinal (GI) tract. The protein encoded by this gene is a motilin receptor which is a member of the G-protein coupled receptor 1 family. This member is a multi-pass transmembrane protein, and is an important therapeutic target for the treatment of hypomotility disorders. [provided by RefSeq, Aug 2011]

Ambry Genetics

Sep 25, 2023

The c.562G>A (p.V188I) alteration is located in exon 1 (coding exon 1) of the MLNR gene. This alteration results from a G to A substitution at nucleotide position 562, causing the valine (V) at amino acid position 188 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
