Characterization of Dysmorphology in Subjects With Creatine Transporter Deficiency

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

Background: Creatine transporter deficiency (CTD) is a genetic disorder that mainly affects the brain in males. CTD causes intellectual disability that can be mild to severe. People with CTD may have seizures and behavioral issues. They may have slow growth and tire easily. CTD may sometimes be confused with autism or other disorders. Better diagnostics are needed. The study team in an NIH study noted that the faces of children with CTD can look similar. For this natural history study, an expert will examine photos of children with CTD. Any shared traits found might help to diagnose CTD. Objective: To look for shared facial features of children with CTD. Eligibility: Males aged 2 to 40 years old with CTD who were in study 17-CH-0020. Design: Some participants in study 17-CH-0020 had pictures taken of their faces. The NIH study team wants to share these photos with a colleague in Canada. This person is an expert at evaluating how genetic disorders affect people s bodies. Participant data collected during the study may also be sent to this expert. This data may include diagnostic images and results from lab tests. Some children did not have their pictures taken during study 17-CH-0020. Parents are asked to take pictures of these children and send them to the study team. These photos can be sent to a secure portal. The photos can also be taken in-person during a clinic visit. The photos may be printed in clinical study journals. But this is not required. Parents will be asked to sign a separate consent before the photos are published....

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Ages Eligible for Study:2 Years to 40 Years
Sexes Eligible for Study:MALE
Accepts Healthy Volunteers:No
Standard Ages:CHILD, ADULT
Inclusion CriteriaExclusion Criteria
  1. 1. Patient is male and between 2-40 years of age, inclusive.
  2. 2. Patient has genomic confirmation of a pathologic mutation in the SLC6A8 gene.
  3. 3. Patient is able to complete study-related procedures within limitations imposed by condition under study.
  4. 4. Patients parents/guardians/caregivers must provide written consent (informed consent) to study-related procedures, and if appropriate, the patient will provide an assent.
  1. 1. Patient has had status epilepticus within 3 months of screening.
  2. 2. Patients has had a seizure that lasts 5 minutes or longer, and a second seizure without recovering consciousness from the first one, or if a person has repeated seizures for 30 minutes or longer.
  3. 3. Patient is unable to comply with the study procedures or has a clinical disease or laboratory abnormality that in the opinion of the investigator would potentially increase the risk of participation.
