Variant summary

Our verdict is Pathogenic. The variant received 20 ACMG points: 20P and 0B. PS1PM2PM5PP3_StrongPP5_Very_Strong

The NM_000260.4(MYO7A):c.3892G>A(p.Gly1298Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000315 in 1,586,002 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 14/22 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Pathogenic in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G1298E) has been classified as Likely pathogenic.

Genes affected

MYO7A (HGNC:7606): (myosin VIIA) This gene is a member of the myosin gene family. Myosins are mechanochemical proteins characterized by the presence of a motor domain, an actin-binding domain, a neck domain that interacts with other proteins, and a tail domain that serves as an anchor. This gene encodes an unconventional myosin with a very short tail. Defects in this gene are associated with the mouse shaker-1 phenotype and the human Usher syndrome 1B which are characterized by deafness, reduced vestibular function, and (in human) retinal degeneration. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2008]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 1298 of the MYO7A protein (p.Gly1298Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Usher syndrome (PMID: 29490346). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 164693). 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 expected to disrupt MYO7A protein function with a positive predictive value of 95%. For these reasons, this variant has been classified as Pathogenic. -

MYO7A c.3892G>A, p.G1298R alters a residue that is completely conserved in all sequenced vertebrates. The variant is homozygous in a Palestinian child with severe to profound pre-lingual hearing loss (Abu Rayyan 2020). The variant is heterozygous in 2/1300 Palestinian controls and absent from gnomAD v2.1.1. 2 -
