Genes affected

RBMS1 (HGNC:9907): (RNA binding motif single stranded interacting protein 1) This gene encodes 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. These proteins have been implicated in such diverse functions as DNA replication, gene transcription, cell cycle progression and apoptosis. Several transcript variants, resulting from alternative splicing and encoding different isoforms, have been described. A pseudogene for this locus is found on chromosome 12.

The c.533G>A (p.G178D) alteration is located in exon 5 (coding exon 5) of the RBMS1 gene. This alteration results from a G to A substitution at nucleotide position 533, causing the glycine (G) at amino acid position 178 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
