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. Variant introduced in the Lund SERPING1 database http://structure.bmc.lu.se/idbase/SERPING1base/ Conflicting classifications of pathogenicity. Variant introduced in ClinVar as VUS by InVitae, San Francisco CA and as likely pathogenic by Research Centre For Medical Genetics, Moscow Russia |
