Variant remarks |
Compound heterozygous proband presenting with a HAE of the intermediate type. Both variants are in trans, c.5C>T maternal allele/c.1045C>T paternal allele, both parents are asymptomatic, suggesting that p.(Leu349Phe) does not impair C1-INH expression and function. Leu327 is a conserved position among serpins (76%); Leu327 is located at the C-terminus of sheet s2B, within the breach functional domain. Leu327 packs against conserved positions in s3A (Tyr272, Trp277), and possibly makes H-bonding with P14 in serpin-protease associated structure. Leu to Phe transition introduces an aromatic side chain that likely generates clashes between Leu327 and Trp277 that could disturb the conformation of S3A and thereby disrupt the RCL insertion into the shutter region. p.Leu349Phe intolerant by SIFT, probably damaging by PolyPhen, disease causing by MutationTaster. Proposed ACMG criteria PS3, PP3, PM3. Submitted to ClinVar as likely benign by InVitae, San Francisco CA, without any reference to bioinformatic support, and as VUS by PreventionGenetics Marshfield WI. |
