Genes affected

RBM17 (HGNC:16944): (RNA binding motif protein 17) This gene encodes an RNA binding protein. The encoded protein is part of the spliceosome complex and functions in the second catalytic step of mRNA splicing. Alternatively spliced transcript variants have been described. Related pseudogenes exist on chromosomes 9 and 15. [provided by RefSeq, Mar 2009]

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=0.1594925).

Collection Method: clinical testing

The c.508A>G (p.M170V) alteration is located in exon 6 (coding exon 5) of the RBM17 gene. This alteration results from a A to G substitution at nucleotide position 508, causing the methionine (M) at amino acid position 170 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
