Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine RCV000155694 SCV000205404 likely pathogenic Rare genetic deafness 2013-06-21 criteria provided, single submitter clinical testing The Thr1822Pro variant in MYO7A has not been reported in individuals affected wi th hearing loss or Usher syndrome. This variant has also not been identified in large European American and African American populations by the NHLBI Exome Sequ encing Project (http://evs.gs.washignton.edu/EVS), which increases the likelihoo d that the variant is pathogenic. However, we cannot exclude that it may be comm on in other populations. Computational analyses (biochemical amino acid properti es, conservation, AlignGVGD, PolyPhen2, and SIFT) suggest that the variant may i mpact the protein, though this information alone is not predictive enough to det ermine pathogenicity. This variant has been identified in trans with a pathogeni c MYO7A variant in this individual's affected son, which increases the likelihoo d of a pathogenic role for this variant. In summary, due to its absence in the g eneral population, the computational data, and its presence in trans with a path ogenic variant in an affected individual, this variant is likely to be pathogeni c, though additional studies are required to fully establish its clinical signif icance.
