Variant summary
Our verdict is Likely benign. The variant received -1 ACMG points: 0P and 1B. BP4
The NM_206933.4(USH2A):c.6134A>T(p.His2045Leu) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000105 in 1,613,990 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict 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. H2045R) has been classified as Likely benign.

Usher syndrome type 2A;C3151138:Retinitis pigmentosa 39 Uncertain:1
- -
not provided Uncertain:1
This sequence change replaces histidine with leucine at codon 2045 of the USH2A protein (p.His2045Leu). The histidine residue is moderately conserved and there is a moderate physicochemical difference between histidine and leucine. This variant is present in population databases (rs111033514, ExAC 0.001%). This variant has not been reported in the literature in individuals affected with USH2A-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C25"). 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. -
