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]

Submissions by phenotype

not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJun 29, 2015p.Ala3Val in exon 01c of MITF: This variant is not expected to have clinical si gnificance because the alanine (Ala) residue at position 3 is not conserved thro ugh species, with Egyptian jerboa, elephant and Cape elephant shrew all having a valine (Val) at this position. Additional computational analyses suggest that this variant may not impact the protein. It has been identified in 1/66732 Eur opean chromosomes and 1/16512 South Asian chromosomes by the Exome Aggregation C onsortium (ExAC, http://exac.broadinstitute.org). -
