• Conservation: PhyloP100: 3.80

Genes affected

SLAMF1 (HGNC:10903): (signaling lymphocytic activation molecule family member 1) Enables SH2 domain binding activity and identical protein binding activity. Involved in several processes, including negative regulation of CD40 signaling pathway; negative regulation of cytokine production; and positive regulation of MAPK cascade. Located in extracellular exosome. [provided by Alliance of Genome Resources, Apr 2022]

The c.911C>T (p.T304I) alteration is located in exon 6 (coding exon 6) of the SLAMF1 gene. This alteration results from a C to T substitution at nucleotide position 911, causing the threonine (T) at amino acid position 304 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
