Genes affected
TBC1D25 (HGNC:8092): (TBC1 domain family member 25) This gene encodes a protein with a TBC domain and functions as a Rab GTPase activating protein. The encoded protein is involved in the fusion of autophagosomes with endosomes and lysosomes. This gene was previously known as ornithine aminotransferase-like 1, but has no similarity to ornithine aminotransferase. [provided by RefSeq, Jan 2017]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.1838G>A (p.R613Q) alteration is located in exon 6 (coding exon 6) of the TBC1D25 gene. This alteration results from a G to A substitution at nucleotide position 1838, causing the arginine (R) at amino acid position 613 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
