Genes affected

SFTPD (HGNC:10803): (surfactant protein D) The protein encoded by this gene is part of the innate immune response, protecting the lungs against inhaled microorganisms and chemicals. The encoded protein may also be involved in surfactant metabolism. [provided by RefSeq, Jul 2015]

The p.Ala295Thr variant in SFTPD has not been previously reported in individuals with surfactant dysfunction, but has been identified in 2/30782 of South Asian chromosomes and 3/111682 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs369866808). Computational pr ediction tools and conservation analysis suggest that the p.Ala295Thr variant ma y not impact the protein, though this information is not predictive enough to ru le out pathogenicity. In summary, the clinical significance of the p.Ala295Thr v ariant is uncertain. ACMG/AMP Criteria applied: BP4 (Richards 2015). -
