Genes affected

SLAMF8 (HGNC:21391): (SLAM family member 8) This gene encodes a member of the CD2 family of cell surface proteins involved in lymphocyte activation. These proteins are characterized by Ig domains. This protein is expressed in lymphoid tissues, and studies of a similar protein in mouse suggest that it may function during B cell lineage commitment. The gene is found in a region of chromosome 1 containing many CD2 genes. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.224G>A (p.R75H) alteration is located in exon 2 (coding exon 2) of the SLAMF8 gene. This alteration results from a G to A substitution at nucleotide position 224, causing the arginine (R) at amino acid position 75 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
