Predictive functional, statistical and structural analysis of CSNK2A1 and CSNK2B variants linked to...

Area of Science:

• Genetics and Molecular Biology
• Neurodevelopmental Disorders
• Biochemistry

Background:

• Okur-Chung Neurodevelopmental Syndrome (OCNDS) and Poirier-Bienvenu Neurodevelopmental Syndrome (POBINDS) are rare neurodevelopmental disorders.
• These syndromes are associated with heterozygous mutations in the CSNK2A1 and CSNK2B genes, encoding protein kinase CK2 subunits CK2α and CK2β.

Purpose of the Study:

• To understand the genetic basis and mutation effects in OCNDS and POBINDS.
• To analyze variants in CSNK2A1 and CSNK2B, identify mutation hotspots, and investigate the functional and structural consequences of CK2α and CK2β mutations.

Main Methods:

• Collected and analyzed all available variants in CSNK2A1 and CSNK2B genes.
• Utilized prediction programs assessing evolutionary conservation, functionality, and structure of CK2α and CK2β missense mutations.
• Compared computational predictions with published experimental data and investigated potential impacts on protein 3D structure and subunit binding.

Main Results:

• Identified mutation hotspots within CSNK2A1 and CSNK2B genes.
• Computational analysis predicted functional and structural consequences for various CK2α and CK2β mutations.
• Results align with existing experimental findings, suggesting predictive utility for future mutation studies.

Conclusions:

• Mutations in CSNK2A1 and CSNK2B have significant functional and structural impacts.
• This study provides a foundation for further research into OCNDS and POBINDS pathogenesis.
• Understanding these genetic and functional bases is essential for elucidating disease mechanisms.
