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]
CD2BP2-DT (HGNC:53029): (CD2BP2 divergent transcript)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 29, 2023The c.2225G>T (p.R742L) alteration is located in exon 9 (coding exon 9) of the TBC1D10B gene. This alteration results from a G to T substitution at nucleotide position 2225, causing the arginine (R) at amino acid position 742 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
