Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000151833 SCV000200306 uncertain significance not specified 2013-10-11 criteria provided, single submitter clinical testing The Arg247Cys variant in SERPINA1, also called the F allele, has been identified in 0.4% (35/8600) of European American chromosomes from a large population by t he NHLBI Exome Sequencing Project ( This vari ant has been reported to affect protein function (Cook 1996) and may contribute to disease when homozygous or when present with other SERPINA1 variants (Ringenb ach 2011). Computational analyses (biochemical amino acid properties, AlignGVGD, PolyPhen2, and SIFT) also support an impact to the protein though their accurac y is not known. In summary, additional information is needed to fully assess the clinical significance of this variant.

Illumina Clinical Services Laboratory,Illumina RCV000148879 SCV001279508 likely benign Alpha-1-antitrypsin deficiency 2017-04-27 criteria provided, single submitter clinical testing This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign.

Department of Laboratory Medicine and Genetics,Trillium Health Partners Credit Valley Hospital RCV000148879 SCV000608326 likely pathogenic Alpha-1-antitrypsin deficiency 2014-12-08 no assertion criteria provided clinical testing Mildly reduced alpha-1-antitrypsin activity. In practice appears to be associated with mild deficiency. Literature opinion divided. Protein levels may be normal but has a decreased ability to inhibit neutrophil elastase & is frequently seen in patients with respiratory symptoms.
