Genes affected

RBMS2 (HGNC:9909): (RNA binding motif single stranded interacting protein 2) The protein encoded by this gene is a member of a small family of proteins which bind single stranded DNA/RNA. These proteins are characterized by the presence of two sets of ribonucleoprotein consensus sequence (RNP-CS) that contain conserved motifs, RNP1 and RNP2, originally described in RNA binding proteins, and required for DNA binding. The RBMS proteins have been implicated in such diverse functions as DNA replication, gene transcription, cell cycle progression and apoptosis. This protein was isolated by phenotypic complementation of cdc2 and cdc13 mutants of yeast and is thought to suppress cdc2 and cdc13 mutants through the induction of translation of cdc2.

Collection Method: clinical testing

The c.49A>G (p.N17D) alteration is located in exon 1 (coding exon 1) of the RBMS2 gene. This alteration results from a A to G substitution at nucleotide position 49, causing the asparagine (N) at amino acid position 17 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
