Genes affected

NEK5 (HGNC:7748): (NIMA related kinase 5) Predicted to enable ATP binding activity; metal ion binding activity; and protein kinase activity. Predicted to be involved in protein phosphorylation. Predicted to act upstream of or within positive regulation of cysteine-type endopeptidase activity and positive regulation of striated muscle cell differentiation. [provided by Alliance of Genome Resources, Apr 2022]

ALG11 (HGNC:32456): (ALG11 alpha-1,2-mannosyltransferase) This gene encodes a GDP-Man:Man3GlcNAc2-PP-dolichol-alpha1,2-mannosyltransferase which is localized to the cytosolic side of the endoplasmic reticulum (ER) and catalyzes the transfer of the fourth and fifth mannose residue from GDP-mannose (GDP-Man) to Man3GlcNAc2-PP-dolichol and Man4GlcNAc2-PP-dolichol resulting in the production of Man5GlcNAc2-PP-dolichol. Mutations in this gene are associated with congenital disorder of glycosylation type Ip (CDGIP). This gene overlaps but is distinct from the UTP14, U3 small nucleolar ribonucleoprotein, homolog C (yeast) gene. A pseudogene of the GDP-Man:Man3GlcNAc2-PP-dolichol-alpha1,2-mannosyltransferase has been identified on chromosome 19. [provided by RefSeq, Aug 2010]
