Genes affected
CD36 (HGNC:1663): (CD36 molecule (CD36 blood group)) The protein encoded by this gene is the fourth major glycoprotein of the platelet surface and serves as a receptor for thrombospondin in platelets and various cell lines. Since thrombospondins are widely distributed proteins involved in a variety of adhesive processes, this protein may have important functions as a cell adhesion molecule. It binds to collagen, thrombospondin, anionic phospholipids and oxidized LDL. It directly mediates cytoadherence of Plasmodium falciparum parasitized erythrocytes and it binds long chain fatty acids and may function in the transport and/or as a regulator of fatty acid transport. Mutations in this gene cause platelet glycoprotein deficiency. Multiple alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Feb 2014]

The CD36 c.332_333delCA (p.Thr111SerfsTer22) variant results in a frameshift and is predicted to result in premature termination of the protein. The p.Thr111SerfsTer22 variant has been reported in at least five studies in which it is found in at least twelve individuals with platelet glycoprotein IV deficiency, including in one in a homozygous state, in five in a compound heterozygous state, and in at least five in a heterozygous state, and in one additional individual with unknown zygosity (Kashiwagi et al. 1994; Yanai et al. 2000; Xu et al. 2013; Li et al. 2015; Masuda et al. 2015). In these studies, all the individuals are reported as generally healthy but failing to express CD36 on their platelets. The p.Thr111SerfsTer22 variant has been described as one of the most common variants associated with platelet glycoprotein IV deficiency in the Southern Chinese population (Xu et al. 2013). The variant was also found in a heterozygous state in three individuals with cerebral malaria (Omi et al. 2002). Control data are unavailable for this variant, which is reported at a frequency of 0.018849 in the East Asian population of the 1000 Genomes Project. Flow cytometry found four of the heterozygous patients were negative for CD36 expression and one heterozygote had a normal phenotype but had significantly reduced CD36 expression (Li et al. 2015; Masuda et al. 2015). Based on the collective evidence, the p.Thr111SerfsTer22 variant is classified as pathogenic for platelet glycoprotein IV deficiency. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

NM_001001547.2:c.332_333delCA in the CD36 gene has an allele frequency of 0.016 in East Asian subpopulation in the gnomAD database. The CD36 c.332_333delCA (p.Thr111SerfsTer22) variant results in a frameshift and is predicted to result in premature termination of the protein. The p.Thr111SerfsTer22 variant has been reported in individuals with platelet glycoprotein IV deficiency, including in one in a homozygous state, in five in a compound heterozygous state with 1228_1239del, Arg386Trp, Gln74Term (PMID: 23966019; 25330908; 25798958). Taken together, we interprete this variant as Pathogenic/Likely pathogenic variant. ACMG/AMP Criteria applied: PVS1; PP4; PM3_Strong. -
