Genetic Variant SFTPD:p.Gly112Arg (chr10-79942487-C-G) – ACMG Classification: Uncertain_significance (4 pts)

Variant summary

Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PM2PP3_Moderate

The NM_003019.5(SFTPD):c.334G>C(p.Gly112Arg) variant causes a missense change. The variant allele was found at a frequency of 0.0000639 in 1,612,864 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G112S) has been classified as Uncertain significance.
