Genes affected

NTM (HGNC:17941): (neurotrimin) This gene encodes a member of the IgLON (LAMP, OBCAM, Ntm) family of immunoglobulin (Ig) domain-containing glycosylphosphatidylinositol (GPI)-anchored cell adhesion molecules. The encoded protein may promote neurite outgrowth and adhesion via a homophilic mechanism. This gene is closely linked to a related family member, opioid binding protein/cell adhesion molecule-like (OPCML), on chromosome 11. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2009]

Ambry Genetics

Dec 26, 2023

The c.53C>G (p.S18C) alteration is located in exon 1 (coding exon 1) of the NTM gene. This alteration results from a C to G substitution at nucleotide position 53, causing the serine (S) at amino acid position 18 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
