PAPD5
P53 Activator Protein 5: A Guardian of Cellular Integrity
Description
The papd5 gene encodes the P53 activator protein 5 (PAPD5), an essential protein involved in cellular stress response. PAPD5 plays a pivotal role in maintaining genomic stability by activating the tumor suppressor p53, a key regulator of cell cycle, apoptosis, and DNA repair.
Associated Diseases
Mutations in the papd5 gene have been implicated in several human diseases, including:
- Li-Fraumeni syndrome: An inherited cancer predisposition disorder characterized by an increased risk of various cancers, including breast, lung, and bone cancers.
- Schmid-Fraccaro syndrome: A rare developmental disorder associated with intellectual disability, microcephaly, and other congenital anomalies.
- Epilepsy: Certain mutations in papd5 have been linked to early-onset epilepsy.
- Cancer: PAPD5 dysregulation has been observed in various types of cancer, contributing to tumor growth and metastasis.
Did you Know ?
According to the National Cancer Institute, individuals with Li-Fraumeni syndrome caused by papd5 mutations have an estimated lifetime risk of developing cancer of up to 80%, significantly higher than the general population.
