Solving Medical Mysteries
Through Team Science

Finding Answers through Sharing

We are always looking for new participants that can help us better understand the medical mysteries plaguing us today. Here, you can learn more about some of our past participants and help us find and connect with others with the same or similar conditions.

If you or someone you know has any of the symptoms or genetic changes listed in these profiles, please contact us.

Each of these pages includes details about our participants. We respect the privacy of all our participants, and sharing information on our site is not a requirement to participate in the study. Only participants who have given us their consent will have information posted to our site.

Female, age 12 with a history of seizures, brain imaging abnormalities, behavioral features (ADHD, hallucinations, and sleepwalking), mild to moderate bilateral sensorineural hearing loss, and distinctive facial features

Participant 179

 

Male, age 13 with a history of seizures, involuntary muscle contractions (dystonia), irregular and involuntary jerky movements on one side of the body (hemiballismus), difficulty walking (gait disturbance), and brain imaging abnormalities caused by a change in the EIF2AK2 gene

Participant 178

 

Male, age 7, with global developmental delay, muscle weakness, hand tremor, increased tone in lower limbs (hypertonia), and facial differences

Participant 177

 

Male, age 4 with global developmental delay, low muscle tone of trunk (hypotonia), seizures, a history of clubbed feet (bilateral talipes equinovarus), head turned persistently to the right (torticollis), and webbing of the penis (penoscrotal fusion)

Participant 176

 

Female, age 4 with seizure-like episodes, laryngeal cleft, difficulty swallowing (dysphagia), events of low blood sugar (recurrent hypoglycemia), and abnormal brain MRI

Participant 175

 

Female, age 5 with seizures (tonic seizures and spasms) that are resistant to treatment (refractory), global developmental delay, autism, and intermittent problems with coordination (gait ataxia)

Participant 174

 

Male, age 4 with seizures (bilateral tonic-clonic with generalized onset, focal impaired awareness seizure), involuntary muscle contractions (dystonia), global developmental delay, and upbeat nystagmus

Participant 173

Female, age 14 with severe epileptic encephalopathy, global developmental delay, and clumsy, broad-based gait

Read More

Participant 172

 
Female, age 9 with severe global developmental delay, muscle tone abnormalities (hypotonia of the trunk, hypertonia of wrists and ankles), tightened muscles and tremor of lower extremities (spasticity), brain abnormalities (cerebellar atrophy, periventricular white matter hyperdensities), and cerebral folate deficiency (decreased CSF 5-methyltetrahydrofolate concentration) thought to be caused by a change in the SPTSSA gene

Participant 171

 

Male, age 25 with absent shoulder muscles (congenital bilateral absence of deltoid muscles), underdeveloped bicep tendons, developmental delay, joint hypermobility, and skeletal abnormalities caused by a change in the CDH2 gene
