Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 0P and 0B.

The NM_001001417.7(TBC1D3B):​c.616G>T​(p.Ala206Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A206T) has been classified as Likely benign.

Genes affected

TBC1D3B (HGNC:27011): (TBC1 domain family member 3B) This gene encodes a protein that is similar to TBC1 domain family, member 3. This protein contains a TBC (Tre-2, Bub2p, and Cdc16p) domain, which is found in proteins involved in RAB GTPase signaling and vesicle trafficking. There are multiple copies of this gene located within a cluster of chemokine genes on chromosome 17q. [provided by RefSeq, Apr 2009]
