Genes affected

SND1 (HGNC:30646): (staphylococcal nuclease and tudor domain containing 1) This gene encodes a transcriptional co-activator that interacts with the acidic domain of Epstein-Barr virus nuclear antigen 2 (EBNA 2), a transcriptional activator that is required for B-lymphocyte transformation. Other transcription factors that interact with this protein are signal transducers and activators of transcription, STATs. This protein is also thought to be essential for normal cell growth. A similar protein in mammals and other organisms is a component of the RNA-induced silencing complex (RISC). [provided by RefSeq, Jul 2016]

The c.506G>A (p.G169D) alteration is located in exon 5 (coding exon 5) of the SND1 gene. This alteration results from a G to A substitution at nucleotide position 506, causing the glycine (G) at amino acid position 169 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
