ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000125 (19/152328) while in subpopulation AMR AF= 0.00118 (18/15298). AF 95% confidence interval is 0.00076. There are 0 homozygotes in gnomad4. There are 11 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.1655G>A (p.S552N) alteration is located in exon 13 (coding exon 13) of the PGM2L1 gene. This alteration results from a G to A substitution at nucleotide position 1655, causing the serine (S) at amino acid position 552 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
