chr1-215674136-T-C
Variant summary
Our verdict is Benign. The variant received -12 ACMG points: 0P and 12B. BP4_StrongBP6_Very_Strong
The NM_206933.4(USH2A):c.13775A>G(p.Gln4592Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000328 in 1,614,164 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. Q4592H) has been classified as Uncertain significance.

not provided Benign:2
- -
In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
not specified Benign:1
p.Gln4592Arg in exon 63 of USH2A: This variant is not expected to have clinical significance due to a lack of conservation across species, including mammals. Of note, over 10 mammals have a Arginine (R) at this position. Additionally, It ha s been identified in 0.14% (16/11566) of Latino chromosomes by the Exome Aggrega tion Consortium (ExAC, http://exac.broadinstitute.org, dbSNP rs201864716). -
