Variant summary
Our verdict is Uncertain significance. The variant received 1 ACMG points: 2P and 1B. PM1BP4
The NM_000260.4(MYO7A):c.6092G>A(p.Arg2031Gln) variant causes a missense change. The variant allele was found at a frequency of 0.0000157 in 1,592,984 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. R2031W) has been classified as Likely benign.

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 2031 of the MYO7A protein (p.Arg2031Gln). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with deafness (PMID: 30733538). ClinVar contains an entry for this variant (Variation ID: 229010). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt MYO7A protein function with a negative predictive value of 95%. 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. -
Reported in a patient with hearing loss in published literature (PMID: 30733538); In silico analysis indicates that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 30733538) -
not specified Uncertain:1
The p.Arg2031Gln variant in MYO7A has not been previously reported in individual s with hearing loss or Usher syndrome, but has been identified in 1/18592 Europe an chromosomes and 1/2270 East Asian chromosomes by the Exome Aggregation Consor tium (ExAC, http://exac.broadinstitute.org). Computational prediction tools do n ot provide strong support for or against an impact to the protein. In summary, t he clinical significance of the p.Arg2031Gln variant is uncertain. -
