Genes affected

RNF183 (HGNC:28721): (ring finger protein 183) Enables ubiquitin protein ligase activity. Involved in positive regulation of endoplasmic reticulum stress-induced intrinsic apoptotic signaling pathway; protein ubiquitination; and response to endoplasmic reticulum stress. Located in endoplasmic reticulum. Is integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.10605556).

The c.485T>G (p.I162S) alteration is located in exon 2 (coding exon 1) of the RNF183 gene. This alteration results from a T to G substitution at nucleotide position 485, causing the isoleucine (I) at amino acid position 162 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
