The variant allele was found at a frequency of 0.644 in 152,138 control chromosomes in the GnomAD database, including 32,366 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.64 (32366 hom., cov: 33)
• Consequence: GLTP NM_016433.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -2.11

Genes affected

GLTP (HGNC:24867): (glycolipid transfer protein) The protein encoded by this gene is similar to bovine and porcine proteins which accelerate transfer of certain glycosphingolipids and glyceroglycolipids between membranes. It is thought to be a cytoplasmic protein. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.753 is higher than 0.05.
