Genes affected

RBM15 (HGNC:14959): (RNA binding motif protein 15) Members of the SPEN (Split-end) family of proteins, including RBM15, have repressor function in several signaling pathways and may bind to RNA through interaction with spliceosome components (Hiriart et al., 2005 [PubMed 16129689]).[supplied by OMIM, Feb 2009]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3700266).

The c.709C>T (p.R237C) alteration is located in exon 1 (coding exon 1) of the RBM15 gene. This alteration results from a C to T substitution at nucleotide position 709, causing the arginine (R) at amino acid position 237 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
