Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000155994 SCV000205706 uncertain significance not specified 2016-06-23 criteria provided, single submitter clinical testing Variant classified as Uncertain Significance - Favor Benign. The p.Pro1220Leu va riant in MYO7A has been reported in 1 Caucasian individual with Usher syndrome w ho also had 2 variants in the USH2A gene sufficient to explain disease and in 1 individual by our laboratory who was also heterozygous for 2 pathogenic variants in 2 different genes (Bonnet 2011, LMM unpublished data). This variant has been identified in 1/9144 European chromosomes by the Exome Aggregation Consortium ( ExAC,; dbSNP rs727504710). Computational predicti on tools and conservation analyses suggest that this variant may impact the prot ein, though this information is not predictive enough to determine pathogenicity . In summary, while the clinical significance of the p.Pro1220Leu variant is unc ertain, its presence in previously reported affected individuals who had alterna te explanations for the hearing loss suggests a more likely benign role for this variant.
