Description

The frequency data for this variant in the population databases is considered unreliable, as metrics indicate insufficient coverage at this position in the ExAC database. 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt STK11 protein function. This variant has not been reported in the literature in individuals with STK11-related conditions. This sequence change replaces alanine with aspartic acid at codon 420 of the STK11 protein (p.Ala420Asp). The alanine residue is weakly conserved and there is a moderate physicochemical difference between alanine and aspartic acid.
