ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.30343717).

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0000263 (4/152232) while in subpopulation SAS AF= 0.000828 (4/4832). AF 95% confidence interval is 0.000282. There are 0 homozygotes in gnomad4. There are 3 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.2051C>G (p.A684G) alteration is located in exon 10 (coding exon 9) of the PPP1R13L gene. This alteration results from a C to G substitution at nucleotide position 2051, causing the alanine (A) at amino acid position 684 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
