Variant summary
Our verdict is Benign. The variant received -18 ACMG points: 0P and 18B. BP4_ModerateBP6_Very_StrongBS1BS2
The NM_153676.4(USH1C):c.2499C>T(p.Ile833Ile) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00137 in 1,614,136 control chromosomes in the GnomAD database, including 25 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Synonymous variant affecting the same amino acid position (i.e. I833I) has been classified as Uncertain significance.

not specified Benign:2
This variant is not expected to have clinical significance because it does not a lter an amino acid residue, is not located near a splice junction, and has a het erozygous allele frequency of 2/76 (2.6%) (rs34581703). -

Usher syndrome type 1C Benign:2
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 likely benign is not then subjected to further curation. The score for this variant resulted in a classification of likely benign for this disease. -
