Research interests

Kit has studied and taught the molecular genetic basis of human disease since 1991. He has contributed to understanding the genetic mechanisms involved in the disorders of Friedreich's ataxia, X-linked cleft palate, severe neural tube defects and rare variants underlying sudden cardiac death. These projects have contributed to discoveries involving trinucleotide repeat expansion pathogenicity, T-Box transcription factor gene disruption and mammalian palatal shelf formation, the role that planar cell polarity genes play in co-ordinated tissue patterning during embryonic development, as well as CNVs possibly underlying Takotsubo cardiomyopathy.

Research expertise

Copy Number Variants in neurological disorders and sudden cardiac death associated with inherited variants within the Pyrophosphatase 2 (PPA2) gene.

Teaching responsibilities

Course convenor and Lecturer in Nursing Science courses:

NURS443 Anatomy and physiology
NURS444 Pathophysiology
NURS427 Pathophysiology
