Genetics of Sanfilippo Syndrome
Sanfilippo syndrome is inherited in an autosomal recessive pattern. In order for a child to develop the syndrome, both parents must carry a copy of the mutated gene, even though they themselves may not exhibit any symptoms. If both parents carry the mutated gene, there is a 25 percent chance of having a healthy child, a 50 percent chance of having a child who is a carrier of the gene, and a 25 percent chance of having a child with Sanfilippo syndrome.
Signs of Neurological Dysfunction in Sanfilippo Syndrome
Sanfilippo syndrome is a rare genetic disorder that primarily affects children in early childhood. Although symptoms may not be noticeable at birth, they gradually manifest as the child grows older. One of the first signs of this condition is a delay in motor skills development, accompanied by behavioral issues such as restlessness, aggression, or anxiety. Sleep disturbances are also commonly observed.
As the disease progresses, children affected by Sanfilippo syndrome experience a gradual decline in their intellectual abilities and skills. Movement disorders, such as difficulty with coordination and muscle control, may become evident. Additionally, seizures are known to develop as the condition advances.
