The SFTPD c.1082dupA variant is predicted to result in a frameshift and premature protein termination (p.Asn361Lysfs*2). To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
