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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJul 10, 2017The c.955+6G>A variant in PAX3 has not been previously reported in individuals w ith hearing loss or Waardenburg syndrome, but has been identified in 2/24024 Afr ican chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broad institute.org/). This variant is located in the 5' splice region. Computational tools do not suggest an impact to splicing. However, this information is not pre dictive enough to rule out pathogenicity. In summary, the clinical significance of the c.955+6G>A variant is uncertain. -
