Genes affected

SERPINE2 (HGNC:8951): (serpin family E member 2) This gene encodes a member of the serpin family of proteins, a group of proteins that inhibit serine proteases. Thrombin, urokinase, plasmin and trypsin are among the proteases that this family member can inhibit. This gene is a susceptibility gene for chronic obstructive pulmonary disease and for emphysema. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2012]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.991
• BS2: High AC in GnomAdExome4 at 7 AD gene.

The c.656T>C (p.F219S) alteration is located in exon 4 (coding exon 4) of the SERPINE2 gene. This alteration results from a T to C substitution at nucleotide position 656, causing the phenylalanine (F) at amino acid position 219 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
