Genes affected

SERPINA3 (HGNC:16): (serpin family A member 3) The protein encoded by this gene is a member of the serpin family of proteins, a group of proteins that inhibit serine proteases. This gene is one in a cluster of serpin genes located on the q arm of chromosome 14. Polymorphisms in this protein appear to be tissue specific and influence protease targeting. Variations in this protein's sequence have been implicated in Alzheimer's disease, and deficiency of this protein has been associated with liver disease. Mutations have been identified in patients with Parkinson disease and chronic obstructive pulmonary disease. [provided by RefSeq, Jun 2020]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0952588).

BS1

Variant frequency is greater than expected in population eas. GnomAdExome4 allele frequency = 0.000771 (1127/1461882) while in subpopulation EAS AF = 0.027 (1070/39700). AF 95% confidence interval is 0.0256. There are 19 homozygotes in GnomAdExome4. There are 541 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

BS2

High Homozygotes in GnomAdExome4 at 19 AR gene
