Variant summary
Our verdict is Uncertain significance. The variant received 4 ACMG points: 4P and 0B. PP3_Strong
The NM_015459.5(ATL3):c.557T>G(p.Leu186Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000376 in 1,595,236 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/22 in silico tools predict a damaging 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. L186P) has been classified as Uncertain significance.

Neuropathy, hereditary sensory, type 1F Uncertain:1
This sequence change replaces leucine with arginine at codon 186 of the ATL3 protein (p.Leu186Arg). The leucine residue is highly conserved and there is a moderate physicochemical difference between leucine and arginine. This variant is present in population databases (rs776366099, ExAC 0.002%). This variant has not been reported in the literature in individuals with ATL3-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
