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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.286A>G (p.I96V) alteration is located in exon 3 (coding exon 2) of the NRROS gene. This alteration results from a A to G substitution at nucleotide position 286, causing the isoleucine (I) at amino acid position 96 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
