ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.04623565).

BS1

Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.0000528 (8/151418) while in subpopulation AMR AF= 0.000461 (7/15168). AF 95% confidence interval is 0.000216. There are 0 homozygotes in gnomad4. There are 3 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

BS2

High AC in GnomAd at 8 AD gene.

The c.272A>G (p.Q91R) alteration is located in exon 3 (coding exon 3) of the THSD4 gene. This alteration results from a A to G substitution at nucleotide position 272, causing the glutamine (Q) at amino acid position 91 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
