Genes affected

DDOST (HGNC:2728): (dolichyl-diphosphooligosaccharide--protein glycosyltransferase non-catalytic subunit) This gene encodes a component of the oligosaccharyltransferase complex which catalyzes the transfer of high-mannose oligosaccharides to asparagine residues on nascent polypeptides in the lumen of the rough endoplasmic reticulum. The protein complex co-purifies with ribosomes. The product of this gene is also implicated in the processing of advanced glycation endproducts (AGEs), which form from non-enzymatic reactions between sugars and proteins or lipids and are associated with aging and hyperglycemia.

PINK1-AS (HGNC:38872): (PINK1 antisense RNA)

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.142 is higher than 0.05.
