Model organisms

Model organisms have been used in the study of HECW2 function. A conditional knockout mouse line called Hecw2^{tm1a(EUCOMM)Wtsi} was generated at the Wellcome Trust Sanger Institute.[6] Male and female animals underwent a standardized phenotypic screen[7] to determine the effects of deletion.[8][9][10][11] Additional screens performed: - In-depth immunological phenotyping[12]

Clinical significance

Mutations in the HECW2 gene have been associated to epilepsy and intellectual disability. These mutations affect one copy of the HECW2 gene and are believed to change the function of the HECW2 protein.[13]
