Variant summary
Our verdict is Benign. Variant got -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2
The NM_000260.4(MYO7A):c.4805G>A(p.Arg1602Gln) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00111 in 1,611,594 control chromosomes in the GnomAD database, including 39 homozygotes. In-silico tool predicts 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. R1602W) has been classified as Likely benign.

Benign, criteria provided, single submitter | clinical testing | GeneDx | Mar 14, 2018 | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. - |

Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Dec 07, 2012 | p.Arg1602Gln in exon 35 of MYO7A: This variant is not expect to have clinical si gnificance because it has been identified in 4.4% (377/8484) of East Asian chrom osomes including 7 homozygotes by the Exome Aggregation Consortium (ExAC, http:/ /exac.broadinstitute.org; dbSNP rs139889944). This variant was reported in 2 ind ividuals with Usher syndrome (Liu 1998, Weston 1998). It was reported in trans with p.Leu651Pro in MYO7A of uncertain significance in two affected siblings (Li u 1998) and to be homozygous in another individual (Weston 1998), which is consi stent with its allele frequency in the general population and insufficient to su pport pathogenicity. - |

Usher syndrome type 1 Benign:1Other:1
Benign, criteria provided, single submitter | clinical testing | Illumina Laboratory Services, Illumina | Mar 06, 2018 | This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. - |
