Genes affected

RBM15B (HGNC:24303): (RNA binding motif protein 15B) Members of the SPEN (Split-end) family of proteins, including RBM15B, 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]

Collection Method: clinical testing

The c.110C>T (p.A37V) alteration is located in exon 1 (coding exon 1) of the RBM15B gene. This alteration results from a C to T substitution at nucleotide position 110, causing the alanine (A) at amino acid position 37 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
