Description

Variant classified as Uncertain Significance - Favor Benign. The p.Lys4578Glu va riant in USH2A has not been previously reported in individuals with hearing loss or Usher syndrome, but has been identified in 4/11568 of Latino chromosomes and 3/66732 of European chromosomes by the Exome Aggregation Consortium (ExAC, http ://exac.broadinstitute.org; dbSNP rs765354805). The lysine (Lys) at position 457 8 is not conserved in mammals or evolutionarily distant species and 2 mammals (c ape elephant shrew and opossum) carry a glutamic acid (Glu) at this position, ra ising the possibility that this change may be tolerated. Additional computationa l prediction tools do not provide strong support for or against an impact to the protein. In summary, while the clinical significance of the p.Lys4578Glu varian t is uncertain, its presence in mammals suggests that it is more likely to be be nign.
