Genes affected

SLAMF9 (HGNC:18430): (SLAM family member 9) This gene encodes a member of the signaling lymphocytic activation molecule family. The encoded protein is a cell surface molecule that consists of two extracellular immunoglobulin domains, a transmembrane domain and a short cytoplasmic tail that lacks the signal transduction motifs found in other family members. Alternative splicing results in multiple transcript variants.[provided by RefSeq, Apr 2009]

The c.209G>A (p.G70E) alteration is located in exon 2 (coding exon 2) of the SLAMF9 gene. This alteration results from a G to A substitution at nucleotide position 209, causing the glycine (G) at amino acid position 70 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
