Genes affected

TBC1D5 (HGNC:19166): (TBC1 domain family member 5) Enables AP-2 adaptor complex binding activity and retromer complex binding activity. Involved in several processes, including macroautophagy; positive regulation of receptor internalization; and retrograde transport, endosome to Golgi. Located in Golgi apparatus; autophagosome; and endosome membrane. Part of retromer complex. Colocalizes with AP-2 adaptor complex and Atg1/ULK1 kinase complex.

Ambry Genetics

Oct 04, 2022

The c.2117G>A (p.R706Q) alteration is located in exon 23 (coding exon 20) of the TBC1D5 gene. This alteration results from a G to A substitution at nucleotide position 2117, causing the arginine (R) at amino acid position 706 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
