Genes affected

RNF121 (HGNC:21070): (ring finger protein 121) The protein encoded by this gene contains a RING finger, a motif present in a variety of functionally distinct proteins and known to be involved in protein-protein and protein-DNA interactions. Several alternatively spliced transcript variants have been noted for this gene, however, not all are likely to encode viable protein products. [provided by RefSeq, Sep 2008]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.95

The c.584A>T (p.D195V) alteration is located in exon 6 (coding exon 6) of the RNF121 gene. This alteration results from a A to T substitution at nucleotide position 584, causing the aspartic acid (D) at amino acid position 195 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
