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]

TOM1 Gene-Disease associations (from GenCC):

• immune system disorder

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics
• immunodeficiency 85 and autoimmunity

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.144 is higher than 0.05.
