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.845C>A (p.A282E) alteration is located in exon 4 (coding exon 4) of the SLAMF9 gene. This alteration results from a C to A substitution at nucleotide position 845, causing the alanine (A) at amino acid position 282 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
