No “dyspraxic gene” has been identified. However many parents of children who have dyspraxia can identify another member of the family with similar difficulties: as dyspraxia is more often found in boys than girls this may be a father, grandfather, uncle or cousin. Sometimes, during the course of an assessment fathers realise that they experienced similar difficulties as a child. They then have to rethink their own life experiences while also supporting their child and partner. Ragu Lingham ( 2009) concluded in his research that there is a hereditary risk factor with coordination difficulties and Michele Lee and Sue Yoxall found in their study (2007) that 32% reported a family history of dyspraxia or co-ordination difficulties.
