ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.119101524).

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000112 (17/152380) while in subpopulation AFR AF= 0.000409 (17/41586). AF 95% confidence interval is 0.00026. There are 0 homozygotes in gnomad4. There are 9 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

BS2

High AC in GnomAd4 at 17 AD gene.

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2299G>C (p.V767L) alteration is located in exon 1 (coding exon 1) of the IRF2BPL gene. This alteration results from a G to C substitution at nucleotide position 2299, causing the valine (V) at amino acid position 767 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
