Genes affected

PAX3 (HGNC:8617): (paired box 3) This gene is a member of the paired box (PAX) family of transcription factors. Members of the PAX family typically contain a paired box domain and a paired-type homeodomain. These genes play critical roles during fetal development. Mutations in paired box gene 3 are associated with Waardenburg syndrome, craniofacial-deafness-hand syndrome, and alveolar rhabdomyosarcoma. The translocation t(2;13)(q35;q14), which represents a fusion between PAX3 and the forkhead gene, is a frequent finding in alveolar rhabdomyosarcoma. Alternative splicing results in transcripts encoding isoforms with different C-termini. [provided by RefSeq, Jul 2008]

p.Val327Ile in exon 7 of PAX3: This variant is not expected to have clinical sig nificance because it has been identified in 0.2% (21/10406) of African chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP). The estimated prevalence of Waardenburg syndrome is 1/42000 (Pingault 2010 ). Therefore, the frequency of this variant is too high to be causative for Waa rdenburg syndrome. -
