UFM1

Chr 13AR

ubiquitin fold modifier 1

Also known as: BM-002, C13orf20, HLD14

UFM1 encodes a ubiquitin-like protein that is covalently attached to target proteins through a process called ufmylation, which is involved in ribosome recycling, DNA damage response, and endoplasmic reticulum stress response. Mutations cause autosomal recessive leukodystrophy, hypomyelinating, 14, a white matter disorder affecting myelination in the central nervous system. The gene shows moderate tolerance to loss-of-function variants (LOEUF 1.035), suggesting some functional redundancy in the ufmylation pathway.
