Genes affected

MAN2C1 (HGNC:6827): (mannosidase alpha class 2C member 1) Predicted to enable alpha-mannosidase activity. Predicted to be involved in oligosaccharide catabolic process. Located in nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

MAN2C1 links:

NEIL1 (HGNC:18448): (nei like DNA glycosylase 1) This gene is a member of the Nei endonuclease VIII-like gene family which encodes DNA glycosylases. The encoded enzyme participates in the DNA repair pathway by initiating base excision repair by removing damaged bases, primarily oxidized pyrimidines. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2012]
