Variant 16-934246-A-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2PP3

The NM_022773.4(LMF1):c.512T>G(p.Phe171Cys) variant causes a missense, splice region change. The variant allele was found at a frequency of 0.0000188 in 1,599,262 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Synonymous variant affecting the same amino acid position (i.e. F171F) has been classified as Likely benign.

The p.F171C variant (also known as c.512T>G), located in coding exon 3 of the LMF1 gene, results from a T to G substitution at nucleotide position 512. The phenylalanine at codon 171 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, the clinical significance of this alteration remains unclear. -
