Within OMIM database (https://www.omim.org), KANK1 deletions of paternal origin have been associated with cerebral palsy and spastic quadriplegia (MIM # 612,900), and subsequent work has suggested a possible role for gene deletions as susceptibility factors for neurodevelopmental disorders: however, a recent review suggests that small deletions involving KANK1 should be considered benign [23]. This evidence concerns the gene KANK1 and cerebral palsy.
