The NM_153676.4(USH1C):​c.1822C>T​(p.Pro608Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000179 in 1,449,326 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 11/18 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P608R) has been classified as Likely pathogenic.

Genes affected
USH1C (HGNC:12597): (USH1 protein network component harmonin) This gene encodes a scaffold protein that functions in the assembly of Usher protein complexes. The protein contains PDZ domains, a coiled-coil region with a bipartite nuclear localization signal and a PEST degradation sequence. Defects in this gene are the cause of Usher syndrome type 1C and non-syndromic sensorineural deafness autosomal recessive type 18. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineSep 15, 2014Variant classified as Uncertain Significance - Favor Benign. The Pro608Ser varia nt in USH1C has not been previously reported in individuals with hearing loss, a nd data from large population studies is insufficient to assess the frequency of this variant. Proline (Pro) at position 608 is not conserved in evolutionarily distant species, raising the possibility that a change at this position may be t olerated. Additional computational prediction tools suggest that the Pro608Ser v ariant may not impact the protein, though this information is not predictive eno ugh to rule out pathogenicity. In summary, while the clinical significance of th e Pro608Ser variant is uncertain, these data suggest that it is more likely to b e benign. -
