Genes affected
GANAB (HGNC:4138): (glucosidase II alpha subunit) This gene encodes the alpha subunit of glucosidase II and a member of the glycosyl hydrolase 31 family of proteins. The heterodimeric enzyme glucosidase II plays a role in protein folding and quality control by cleaving glucose residues from immature glycoproteins in the endoplasmic reticulum. Expression of the encoded protein is elevated in lung tumor tissue and in response to UV irradiation. Mutations in this gene cause autosomal-dominant polycystic kidney and liver disease.

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -4 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), GANAB. . Gene score misZ 2.2404 (greater than the threshold 3.09). Trascript score misZ 3.2543 (greater than threshold 3.09). GenCC has associacion of gene with polycystic kidney disease 3 with or without polycystic liver disease, autosomal dominant polycystic kidney disease.
BP4
Computational evidence support a benign effect (MetaRNN=0.35594058).
BS2
High AC in GnomAd4 at 15 AD gene.
