Variant remarks Nomenclature: Variant is also known as c.813_815delCAA. The HGVS notation prescibed that on the forward strand it should be CAA at position c.816_818.
Recurrent variant.
In frame deletion; p.(Asn272del) affects a N-glycosylation site; the protein sequence for the Asn272 glycosylation site is NN(272)KIS. Asn272 deletion disrupts the recognition site, thereby altering protein folding and function; thus Asn272del is deleterious as demonstrated by cultured cells by Ren et al (2025).
Asn250 is located at the end of helix F, close to Sheet 3A, with H-bonding with Ala245. Asn250 is a highly exposed residue within the shutter region.
p.(Asn272del) is poorly biosynthesized in recombinant expression studies (Ren et al 2023), then classifying p.(Asn272del) within class II/III (ie., disturbed insertion of the RCL, conformational transition with spontaneous self or mutual insertion of the RCL). The c.816_818del variant in SERPING1 meets ACMG/ClinGen criteria to be classified as likely pathogenic: PP4_Str, PM4, PS4_Mod, PM2_Sup.
