Genes affected

ALG10 (HGNC:23162): (ALG10 alpha-1,2-glucosyltransferase) This gene encodes a membrane-associated protein that adds the third glucose residue to the lipid-linked oligosaccharide precursor for N-linked glycosylation. That is, it transfers the terminal glucose from dolichyl phosphate glucose (Dol-P-Glc) onto the lipid-linked oligosaccharide Glc2Man9GlcNAc(2)-PP-Dol. The rat protein homolog was shown to specifically modulate the gating function of the rat neuronal ether-a-go-go (EAG) potassium ion channel. [provided by RefSeq, Jan 2010]

The c.557G>A (p.R186Q) alteration is located in exon 3 (coding exon 3) of the ALG10 gene. This alteration results from a G to A substitution at nucleotide position 557, causing the arginine (R) at amino acid position 186 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
