Genetic Variant IFI35:p.Phe158Leu (chr17-43013574-C-G) – ACMG Classification: Uncertain_significance (1 pts)

Variant summary

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

The NM_001330230.2(IFI35):c.474C>G(p.Phe158Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000471 in 1,614,046 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts 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. F158Y) has been classified as Uncertain significance.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.480C>G (p.F160L) alteration is located in exon 5 (coding exon 5) of the IFI35 gene. This alteration results from a C to G substitution at nucleotide position 480, causing the phenylalanine (F) at amino acid position 160 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
