Genes affected

MITF (HGNC:7105): (melanocyte inducing transcription factor) The protein encoded by this gene is a transcription factor that contains both basic helix-loop-helix and leucine zipper structural features. The encoded protein regulates melanocyte development and is responsible for pigment cell-specific transcription of the melanogenesis enzyme genes. Heterozygous mutations in the this gene cause auditory-pigmentary syndromes, such as Waardenburg syndrome type 2 and Tietz syndrome. [provided by RefSeq, Aug 2017]

The p.Glu20Asp variant in MITF has not been previously reported in individuals w ith hearing loss or Waardenburg syndrome. This variant has been identified in 1 /14988 European chromosomes by the Exome Aggregation Consortium (ExAC, http://ex ac.broadinstitute.org; dbSNP rs780642512). Computational prediction tools and co nservation analyses do not provide strong support for or against an impact to th e protein. In summary, the clinical significance of the p.Glu20Asp variant is un certain. -
