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]

NM_001001547.2:c.268C>T in the CD36 gene has an allele frequency of 0.014 in East Asian subpopulation in the gnomAD database. The c.268C>T (p.Pro90Ser) variant previously known as c.478C>T, has been reported in 5 homozygous, and 3 compound heterozygous individuals (two with 1159A insertion and one with 1447C) with type I CD36 deficiency (PMID: 11950861). In vitro functional provide support that this variant confers reduced expression in patient cell lines (PMID: 25798958; 7533783). Taken together, we interprete this variant as Pathogenic/Likely pathogenic variant. ACMG/AMP Criteria applied: PM3_Strong; PS3; PP4. -

Across a selection of the available literature, the CD36 c.268C>T (p.Pro90Ser) missense variant has been identified in at least 18 individuals with platelet glycoprotein IV deficiency, including in a homozygous state in at least 11 patients, in a compound heterozygous state in at least five patients, in one individual who was homozygous for the p.Pro90Ser variant and heterozygous for an insertion variant, and in one individual who carried the p.Pro90Ser variant, an insertion variant, and an additional missense variant (Kashiwagi H et al. 1993; Yanai H et al. 2000a; Hanawa et al. 2002). The p.Pro90Ser variant was reported in 0-3.5% of controls, but the allele frequencies were significantly higher in patients (24.5-28.6%) (Yanai et al. 2000a; Yanai et al. 2000b). The p.Pro90Ser variant is reported at a frequency of 0.04088 in the Japanese from Tokyo, Japan population of the 1000 Genomes Project. Functional studies showed that the p.Pro90Ser variant prevented maturation of the CD36 protein leading to degradation of the mutated precursor (Kashiwagi et al. 1995). The Pro90 residue is conserved in all members of the CD36 family. Based on the collective evidence, the p.Pro90Ser 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. -

The p.Pro90Ser variant in CD36, previously known as c.478C>T, has been reported in at least 17 homozygous, and 9 compound heterozygous individuals (predominantly individuals of Asian descent) with CD36 deficiency (type I or II, also known as platelet glycoprotein IV deficiency) (Kashiwagi 1995 PMID: 7533783, Yanai 2000a PMID: 11019968, Yanai 2000b PMID: 10946357, Kajihara 2001 PMID: 11718687, Hanawa 2002 PMID: 11950861, Hames 2014 PMID: 24917573, and Masuda 2015 PMID: 25798958). This variant also segregated with disease in 3 family members from 3 families (Yanai 2000a PMID: 11019968, Hanawa 2002 PMID: 11950861, Hames 2014 PMID: 24917573). In vitro functional provide support that this variant confers reduced expression in patient cell lines (Kashiwagi 1995 PMID: 7533783 and Masuda 2015 PMID: 25798958). This variant has also been reported in ClinVar (Variation ID 13535). This variant has been identified in 1.43% (284/19884) of East Asian chromosomes by gnomAD (http://gnomAD.broadinstitute.org). In summary, the p.Pro90Ser variant meets criteria to be classified as pathogenic for CD36 deficiency in an autosomal recessive manner based upon its occurrence in affected individuals and available functional studies.

Variant summary: CD36 c.268C>T (p.Pro90Ser) results in a non-conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant allele was found at a frequency of 0.0011 in 250710 control chromosomes, predominantly at a frequency of 0.015 within the East Asian subpopulation in the gnomAD database, including 10 homozygotes. Due to the possibility of sub-clinical presentation and/or lack of phenotype information in this cohort, this frequency does not allow conclusions about variant significance. The c.268C>T has been reported in the literature as a homozygous genotype in multiple individuals affected with features of type 1 CD36 deficiency (example, Kashiwagi_1995, Hames_2014, Masuda_2015, Hanawa_2002). Some of these studies also reported the variant as a heterozygous genotype in individuals with type II CD36 deficiency. These data indicate that the variant is likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported although one study has reported that this variant leads to CD36 deficiency via a defect in post-translational modification (Kashiwagi_1995). Four submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. The following publications have been ascertained in the context of this evaluation (PMID: 24917573, 7533783, 25798958, 11019968, 11950861). All submitters classified the variant as pathogenic/likely pathogenic citing overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as VUS-possibly pathogenic. -
