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]

The c.1265A>G (p.Q422R) alteration is located in exon 12 (coding exon 12) of the TOM1L2 gene. This alteration results from a A to G substitution at nucleotide position 1265, causing the glutamine (Q) at amino acid position 422 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
