Genetic Cerebral Palsy, Up To 25% Of Patients With Cerebral Palsy Have Genetic Cause: Birth-related factors like prematurity have been linked to cerebral palsy, or CP. Birth injury or asphyxia come to many physicians’ minds when they think of CP. That idea has spread throughout neurology, orthopaedics, and the general public.”
This is true for many kids. But of the over 700,000 Americans with CP, roughly 20% have no clear explanation for the disorder’s origin.
Genetic Cerebral Palsy, Up To 25% Of Patients With Cerebral Palsy Have Genetic Cause
Srivastava and colleagues discovered in a groundbreaking study that up to 1 in 4 CP patients have a genetic disorder.
Historically, clinicians diagnosed CP in children with muscle tightness and developmental delay without knowing the cause. We can now look into these causes in more depth.
Focusing on CP genetic contributors should aid diagnosis and possibly lead to new treatment plans for some patients.
In addition to being descriptive, a precise diagnosis for children with CP now has the scientific knowledge to provide answers and possibly treat some of the underlying conditions.
The findings may also help alleviate guilt associated with a child’s CP diagnosis. The belief that birth factors cause CP has made some families feel guilty. The condition of their child is frequently questioned by parents.
Cerebral Palsy Genetics
The research team sequence the DNA of 50 CP patients through the Children’s Rare Disease Cohorts initiative. 10 years old on average. They had clinical and MRI tests.
Each group had three patients.
- 20, such as premature birth, a brain bleed, or perinatal asphyxia or hypoxia.
- No known CP risk factors.
- “CP masqueraders” had most of the CP symptoms but their condition was deteriorating. (CP is a non-progressive disease.)
“They wanted to reflect the patients they see.”
Total causative or “likely causative” genetic variants found in 13 patients (26%) by sequencing The CP masqueraders had the highest yield, detecting mutations in 60% of patients. Seven of 24 (29%) of patients with CP and no known risk factors had a genetic cause.
Sequencing revealed mutations in three of 20 patients (15%) with known CP risk factors. One had a rare genetic disorder linked to early stroke. And two had unrelated genetic conditions.
A genetic Diagnosis In CP
In some cases, genetic findings influenced patient care.
As a result of a gene mutation, one patient was referred to the metabolism clinic. One was referred for ocular and kidney evaluations. A third has a mutation link to a neurodegenerative disease. This notified his care team to monitor his condition.
Based on their findings, the researchers suggest:
Consider a genetic cause for any child with CP who has no known risk factors or who has CP-like features but is deteriorating.
Consider genetic testing for children with known CP risk factors. Such as congenital anomalies or other affected family members.
Reevaluate CP children on a regular basis to make sure no new symptoms or features have emerged.
Precision In Diagnosis And Treatment
Shore hopes that in the future, doctors and researchers can “diagnose many more children, particularly CP masqueraders.” This study is only the beginning.”
The programme has discovered dozens of genetic epilepsy causes, some treatable.
“More children with CP, epilepsy, and other neurodevelopmental disorders will benefit from precise diagnosis and treatment.”
