Deregulated expression of PAX3 has been observed in tumors like rhabdomyosarcoma and melanomas.
Mutations in the PAX3 gene are responsible for the condition in the majority of Waardenburg syndrome (WS) patients.
- Mutations in PAX3 have been found in WS type 3 (WS3) that is distinguished by musculoskeletal abnormalities, and in a family with a rare subtype of WS, craniofacial-deafness-hand syndrome (CDHS), characterized by dysmorphic facial features, hand abnormalities, and absent or hypoplastic nasal and wrist bones.
germline mutations of PAX3 in
- Waardenburg syndrome type I (MIM.193500)
- Waardenburg syndrome type III (MIM.148820)
- mild Waardenburg syndrome and spina bifida (7897628)
- craniofacial-deafness-hand syndrome (MIM.122880)
PAX3/FOXO1A fusion gene in alveolar rhabdomyosarcoma
Expression of PAX3 was upregulated in high-grade glioma tissues compared with that in low-grade and normal brain tissues, and increased with ascending tumor World Health Organization (WHO) grades (22231626)
- PAX3 might be an intrinsic regulator of progression in glioma cells and it might serve as a prognostic factor for this dismal disease. (22231626)
