Genes affected

TBC1D1 (HGNC:11578): (TBC1 domain family member 1) TBC1D1 is the founding member of a family of proteins sharing a 180- to 200-amino acid TBC domain presumed to have a role in regulating cell growth and differentiation. These proteins share significant homology with TRE2 (USP6; MIM 604334), yeast Bub2, and CDC16 (MIM 603461) (White et al., 2000 [PubMed 10965142]).[supplied by OMIM, Mar 2008]

The TBC1D1 c.62T>A variant is predicted to result in the amino acid substitution p.Phe21Tyr. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0071% of alleles in individuals of European (non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
