Laboratory for Molecular Medicine,Partners HealthCare Personalized Medicine RCV000036193 SCV000059845 pathogenic Rare genetic deafness 2016-08-23 criteria provided, single submitter clinical testing The p.Leu1858Pro variant in MYO7A has been reported in at least 10 probands with Usher syndrome who were either homozygous for the variant or compound heterozyg ous with a second pathogenic or likely pathogenic variant in MYO7A (Bharadwaj 20 00, Roux 2006, Jacobson 2008, Blanchet 2007, Roux 2011, LeQuesne Stabej 2012, LM M data). It has been identified in 3/55658 European chromosomes by the Exome Agg regation Consortium (http://exac.broadinstitute.org/; dbSNP rs368657015), which is low enough to be consistent with the carrier frequency in the general populat ion. In summary, this variant meets criteria to be classified as pathogenic for Usher syndrome in an autosomal recessive manner based on its presence in homozyg osity or compound heterozygosity with a second pathogenic allele in many individ uals with Usher syndrome, and low frequency in the general population.

The c.5573T>C (p.Leu1858Pro) variant has been identified in a compound heterozygous state in at least six affected individuals, including five with Usher syndrome type 1 and one with autosomal recessive nonsyndromic hearing loss (Roux et al. 2006; Jacobson et al. 2008; Roux et al. 2011; Le Quesne Stabej et al. 2012; Bademci et al. 2016). One additional individual with Usher syndrome type 1 was heterozygous for the p.Leu1858Pro variant and another missense variant, but the phase of the variants was unclear (Bharadwaj et al. 2000). The variant has not been reported in conjunction with autosomal dominant nonsyndromic hearing loss. The p.Leu1858Pro variant was absent from 2148 control chromosomes and is reported at a frequency of 0.000056 in the European (non-Finnish) population of the Genome Aggregation Database. Based on the collective evidence, the p.Leu1858Pro variant is classified as pathogenic for MYO7A-related disorders. Note: While the p.Leu1858Pro variant has not been reported in conjunction with autosomal dominant nonsyndromic hearing loss, disease risk cannot be ruled out. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population.
