Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_006215.4(SERPINA4):​c.236C>T​(p.Pro79Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000384 in 1,613,972 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P79S) has been classified as Uncertain significance.

Genes affected
SERPINA4 (HGNC:8948): (serpin family A member 4) Predicted to enable serine-type endopeptidase inhibitor activity. Predicted to be involved in negative regulation of endopeptidase activity. Located in extracellular exosome. Biomarker of diabetic retinopathy. [provided by Alliance of Genome Resources, Apr 2022]
SERPINA5 (HGNC:8723): (serpin family A member 5) 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. This family member is a glycoprotein that can inhibit several serine proteases, including protein C and various plasminogen activators and kallikreins, and it thus plays diverse roles in hemostasis and thrombosis in multiple organs.
