Nonsyndromic Deafness Uncertain:1
To the best of our knowledge, this variant has not previously been reported in gene-specific databases or the literature; but has been seen at low frequency in individuals of South Asian ancestry reported in population databases (gnomAD, ExAC). In silico analyses all predict an impact on the protein. The amino acid immediately adjacent to this variant is also a leucine; as reported extensively in the literature, mutation of this amnio acid to proline (p.Leu90Pro) is pathogenic. -
