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]

May 04, 2023

The c.401C>T (p.T134I) alteration is located in exon 3 (coding exon 3) of the ALG10 gene. This alteration results from a C to T substitution at nucleotide position 401, causing the threonine (T) at amino acid position 134 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
