Genes affected

ORMDL3 (HGNC:16038): (ORMDL sphingolipid biosynthesis regulator 3) Involved in ceramide metabolic process. Acts upstream of or within several processes, including negative regulation of B cell apoptotic process; negative regulation of ceramide biosynthetic process; and positive regulation of protein localization to nucleus. Located in endoplasmic reticulum. Part of SPOTS complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.82).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0982 is higher than 0.05.
