Genes affected

PLTP (HGNC:9093): (phospholipid transfer protein) The protein encoded by this gene is one of at least two lipid transfer proteins found in human plasma. The encoded protein transfers phospholipids from triglyceride-rich lipoproteins to high density lipoprotein (HDL). In addition to regulating the size of HDL particles, this protein may be involved in cholesterol metabolism. At least two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0212 (3213/151208) while in subpopulation NFE AF = 0.0303 (2053/67734). AF 95% confidence interval is 0.0292. There are 40 homozygotes in GnomAd4. There are 1610 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 40 AR gene
