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]

SLAMF9 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0032785237).
• BP6: Variant 1-159953444-C-T is Benign according to our data. Variant chr1-159953444-C-T is described in ClinVar as [Benign]. Clinvar id is 767714.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0763 is higher than 0.05.
