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.

The c.1229T>C (p.F410S) alteration is located in exon 16 (coding exon 13) of the TBC1D5 gene. This alteration results from a T to C substitution at nucleotide position 1229, causing the phenylalanine (F) at amino acid position 410 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
