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]

CHAF1A (HGNC:1910): (chromatin assembly factor 1 subunit A) Chromatin assembly factor I (CAF1) is a nuclear complex consisting of p50, p60 (CHAF1B; MIM 601245), and p150 (CHAF1A) subunits that assembles histone octamers onto replicating DNA in vitro (Kaufman et al., 1995 [PubMed 7600578]).[supplied by OMIM, Mar 2008]

CHAF1A Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder
