In 10% to 15% of cases, there is no clear cause of CP. There is increasing recognition that genetics plays a part, but no standardized approach to genetic testing in patients with CP exists. In this study we asked the question whether both people with and without known risk factors for CP should have genetic testing.
Cohort-based whole exome and whole genome sequencing and copy number variant (CNV) studies have identified genetic etiologies for a sizable proportion of patients with cerebral palsy (CP). These findings indicate that genetic mutations collectively comprise an important cause of CP.
Drooling is an important problem for many individuals with CP and there are a number of interventions available to treat symptoms. If an individual with CP or their caregiver have concerns about drooling it is important to discuss with a health care provider. Care pathways such as the AACPDM pathway can be a starting point for shared decision making. In all cases, working together as a team is important in choosing the best alternative. Children and adults with CP may have trouble with drooling, or saliva management. In the medical world, drooling is referred to as sialorrhea. Saliva plays an important role in eating but also can interfere with airway clearance and breathing, as well as social participation. When drooling has this kind of impact it becomes important to consider intervention.
An international study recently published in the journal Nature Genetics has provided the first firm evidence that for a substantial number of people, their cerebral palsy (CP) may be caused by a genetic mutation, or mis-spelling in the body’s DNA blueprint.
"In addition to commonly associated environmental factors, genomic factors may cause cerebral palsy. We performed whole-exome sequencing of 250 parent–offspring trios, and observed enrichment of damaging de novo mutations in cerebral palsy cases."
