Genes affected

SERPINA10 (HGNC:15996): (serpin family A member 10) The protein encoded by this gene belongs to the serpin family. It is predominantly expressed in the liver and secreted in plasma. It inhibits the activity of coagulation factors Xa and XIa in the presence of protein Z, calcium and phospholipid. Mutations in this gene are associated with venous thrombosis. Alternatively spliced transcript variants have been found for this gene.[provided by RefSeq, May 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.29665738).

Jun 02, 2023

The c.1030C>A (p.Q344K) alteration is located in exon 4 (coding exon 3) of the SERPINA10 gene. This alteration results from a C to A substitution at nucleotide position 1030, causing the glutamine (Q) at amino acid position 344 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
