ZFP57

ZFP57 is a zinc finger protein that plays a crucial role in the epigenetic regulation of genomic imprinting. It is encoded by the ZFP57 gene in humans.

Function

ZFP57 is a transcription factor that binds to a specific sequence of DNA, known as the imprinting control region (ICR). This binding helps maintain the methylation status of imprinted genes during early embryogenesis. Imprinted genes are those that are expressed in a parent-of-origin-specific manner. If the ZFP57 gene is mutated, it can lead to a loss of imprinting and cause various developmental disorders.

Clinical significance

Mutations in the ZFP57 gene have been associated with a rare genetic disorder known as Transient Neonatal Diabetes Mellitus (TNDM). This condition is characterized by diabetes that begins in infancy and usually resolves by the age of 18 months. However, individuals with TNDM are at a higher risk of developing diabetes later in life.
