Abstract:

BACKGROUND: As a main antigen of platelet, CD36 antigen is also known as platelet glycoprotein IV (GPIV). The mutation of CD36 gene may result in deficiency of the antigen.
OBJECTIVE: To identify a novel CD36 allele.
METHODS: DNA was isolated from peripheral blood sample, and 12 coding regions of CD36 gene were amplified by PCR. Sequencing-based typing was used to analyze the sequence of the target regions. The derived sequences were aligned with the standard sequence of NG_008192 in GenBank to identify the novel allele.
RESULTS AND CONCLUSION: 1142 T>G mutation was detected in exon 12 of CD36 gene of the proband, and the other regions were consistent with the standard sequence. No data or report about 1142 T>G was found in GenBank or National Center for Biotechnology Information (NCBI), and thus it was reported to GenBank and received by number KM275213. 1142 T>G results in amino acid 381 Leu>Ser of the CD36 protein. There is a big
difference in hydrophilia and polarity of the two amino acids. Also the 381 amino acid locates in highly conserved region. Thus it is speculated that 1142 T>G may reduce or vanish the activity of the protein.
