Genes affected

TOM1L2 (HGNC:11984): (target of myb1 like 2 membrane trafficking protein) This gene belongs to a small gene family whose members have an N-terminal VHS domain followed by a GAT domain; domains which typically participate in vesicular trafficking. The canonical protein encoded by this gene also has a C-terminal clathrin binding motif. This protein has been shown to interact with Tollip, clathrin and ubiquitin and is thought to play a role in endosomal sorting. This gene resides in the 3.7 Mb deletion of chromosome region 17p11.2 that is associated with Smith-Magenis syndrome. Alternative splicing results in multiple transcript variants encoding distinct proteins. [provided by RefSeq, Apr 2017]

Ambry Genetics

Sep 22, 2022

The c.1519C>G (p.L507V) alteration is located in exon 15 (coding exon 15) of the TOM1L2 gene. This alteration results from a C to G substitution at nucleotide position 1519, causing the leucine (L) at amino acid position 507 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
