ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BP4

Computational evidence support a benign effect (MetaRNN=0.23649111).

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0000591 (9/152222) while in subpopulation NFE AF= 0.000132 (9/68026). AF 95% confidence interval is 0.000068. There are 0 homozygotes in gnomad4. There are 4 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.11944G>A (p.E3982K) alteration is located in exon 71 (coding exon 70) of the HECTD4 gene. This alteration results from a G to A substitution at nucleotide position 11944, causing the glutamic acid (E) at amino acid position 3982 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
