Genes affected

NLN (HGNC:16058): (neurolysin) This gene encodes a member of the metallopeptidase M3 protein family that cleaves neurotensin at the Pro10-Tyr11 bond, leading to the formation of neurotensin(1-10) and neurotensin(11-13). The encoded protein is likely involved in the termination of the neurotensinergic signal in the central nervous system and in the gastrointestinal tract.[provided by RefSeq, Jun 2010]

Collection Method: clinical testing

The c.71T>C (p.M24T) alteration is located in exon 2 (coding exon 2) of the NLN gene. This alteration results from a T to C substitution at nucleotide position 71, causing the methionine (M) at amino acid position 24 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
