Invitae RCV000201848 SCV000961591 likely pathogenic Alpha-1-antitrypsin deficiency 2020-10-08 criteria provided, single submitter clinical testing This sequence change replaces leucine with proline at codon 65 of the SERPINA1 protein (p.Leu65Pro). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs28931569, ExAC 0.008%). This variant has been observed on the opposite chromosome (in trans) from other pathogenic variants in individuals affected with alpha 1-antitrypsin deficiency (PMID: 9635295, 3262617). This finding is consistent with autosomal recessive inheritance, and suggests that this variant contributes to disease. This variant is also known as M procida and p.Leu41Pro in the literature. ClinVar contains an entry for this variant (Variation ID: 17971). Experimental studies have shown that this missense change disrupts alpha 1-antitrypsin activity (PMID: 14767073). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
