Genes affected

NRROS (HGNC:24613): (negative regulator of reactive oxygen species) Enables transforming growth factor beta binding activity. Predicted to be involved in several processes, including microglia development; sequestering of TGFbeta in extracellular matrix; and transforming growth factor beta1 activation. Located in cell surface. [provided by Alliance of Genome Resources, Apr 2022]

PIGX (HGNC:26046): (phosphatidylinositol glycan anchor biosynthesis class X) This gene encodes a type I transmembrane protein in the endoplasmic reticulum (ER). The protein is an essential component of glycosylphosphatidylinositol-mannosyltransferase I, which transfers the first of the four mannoses in the GPI-anchor precursors during GPI-anchor biosynthesis. Studies in rat indicate that the protein is translated from a non-AUG translation initiation site. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Oct 2009]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.050764114).
