Topic: Genetics and APOE
Humans have three major apolipoprotein E (ApoE) alleles (APOE; ε2, ε3 and ε4) that produce three ApoE protein isoforms. The ε2 allele encodes the ApoE2 isoform (Cys112, Cys158), whereas ε3 encodes the wild-type ApoE3 isoform (Cys112, Arg158) and ε4 encodes the ApoE4 isoform (Arg112, Arg158). Because the type of ApoE expressed is related to sporadic Alzheimer's disease risk and familial hyperlipidemia, many clinical studies have utilized ApoE typing in recent years. ApoE serotyping is based on the correlation between ApoE genotype and isoform; it is therefore possible to determine the genotype from the blood ApoE isoform combination. Serotyping ApoE using mass spectrometry promises highly accurate results while requiring minimal amounts of blood and reagents, resulting in lower costs, which suggest that proteomic-based ApoE serotyping may eventually become a routine clinical laboratory test. Not limited to ApoE, proteomic analysis of human samples could be used to intentionally determine - and perhaps unintentionally reveal - personal genetic information.

How this study scored 38/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 21 of the 56 points we could judge it on, which is 38 out of 100.
