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]

SFTPD (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0016386211).
• BP6: Variant 10-79938055-C-T is Benign according to our data. Variant chr10-79938055-C-T is described in ClinVar as [Benign]. Clinvar id is 165213.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.121 is higher than 0.05.
