Genes affected

MLN (HGNC:7141): (motilin) This gene encodes a small peptide hormone that is secreted by cells of the small intestine to regulate gastrointestinal contractions and motility. Proteolytic processing of the secreted protein produces the mature peptide and a byproduct referred to as motilin-associated peptide (MAP). Three transcript variants encoding different preproprotein isoforms but the same mature peptide have been found for this gene. [provided by RefSeq, May 2010]

Dec 04, 2024

The c.79G>A (p.V27I) alteration is located in exon 2 (coding exon 1) of the MLN gene. This alteration results from a G to A substitution at nucleotide position 79, causing the valine (V) at amino acid position 27 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
