Genes affected

UBXN6 (HGNC:14928): (UBX domain protein 6) Involved in ERAD pathway; endosome to lysosome transport via multivesicular body sorting pathway; and macroautophagy. Located in bounding membrane of organelle and cytosol. Is extrinsic component of membrane. Part of endosome and protein-containing complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1262C>T (p.A421V) alteration is located in exon 11 (coding exon 11) of the UBXN6 gene. This alteration results from a C to T substitution at nucleotide position 1262, causing the alanine (A) at amino acid position 421 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
