Genes affected

TBC1D10B (HGNC:24510): (TBC1 domain family member 10B) Small G proteins of the RAB family (see MIM 179508) function in intracellular vesicle trafficking by switching from the GTP-bound state to the GDP-bound state with the assistance of guanine nucleotide exchange factors (GEFs; see MIM 609700) and GTPase-activating proteins (GAPs). TBC1D10B functions as a GAP for several proteins of the Rab family (Ishibashi et al., 2009 [PubMed 19077034]).[supplied by OMIM, Nov 2010]

Ambry Genetics

Feb 05, 2024

The c.2203C>T (p.R735W) alteration is located in exon 9 (coding exon 9) of the TBC1D10B gene. This alteration results from a C to T substitution at nucleotide position 2203, causing the arginine (R) at amino acid position 735 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
