Genes affected

TOM1 (HGNC:11982): (target of myb1 membrane trafficking protein) This gene was identified as a target of the v-myb oncogene. The encoded protein shares its N-terminal domain in common with proteins associated with vesicular trafficking at the endosome. It is recruited to the endosomes by its interaction with endofin. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

Feb 15, 2023

The c.50T>G (p.I17S) alteration is located in exon 1 (coding exon 1) of the TOM1 gene. This alteration results from a T to G substitution at nucleotide position 50, causing the isoleucine (I) at amino acid position 17 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
