Variant 10-79942019-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 2P and 1B. PM2BP4

The NM_003019.5(SFTPD):c.485C>T(p.Ala162Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000124 in 1,613,940 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A162T) has been classified as Uncertain significance.

The c.485C>T (p.A162V) alteration is located in exon 5 (coding exon 4) of the SFTPD gene. This alteration results from a C to T substitution at nucleotide position 485, causing the alanine (A) at amino acid position 162 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
