Genes affected
ALG5 (HGNC:20266): (ALG5 dolichyl-phosphate beta-glucosyltransferase) This gene encodes a member of the glycosyltransferase 2 family. The encoded protein participates in glucosylation of the oligomannose core in N-linked glycosylation of proteins. The addition of glucose residues to the oligomannose core is necessary to ensure substrate recognition, and therefore, effectual transfer of the oligomannose core to the nascent glycoproteins. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Nov 2008]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.926G>A (p.R309Q) alteration is located in exon 10 (coding exon 10) of the ALG5 gene. This alteration results from a G to A substitution at nucleotide position 926, causing the arginine (R) at amino acid position 309 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
