Genes affected

PRAMEF12 (HGNC:22125): (PRAME family member 12) Predicted to be involved in several processes, including negative regulation of apoptotic process; negative regulation of transcription, DNA-templated; and positive regulation of cell population proliferation. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
• BP7: Synonymous conserved (PhyloP=-5.38 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0141 (2140/151334) while in subpopulation SAS AF= 0.0335 (160/4772). AF 95% confidence interval is 0.0293. There are 0 homozygotes in gnomad4. There are 1108 alleles in male gnomad4 subpopulation. This position pass quality control queck.
