2q24 microdeletion syndrome is a chromosomal anomaly consisting of a partial long arm deletion of chromosome 2 and characterized clinically by a wide range of manifestations (depending on the specific region deleted) which can include seizures, microcephaly, dysmorphic features, cleft palate, eye abnormalities (coloboma, cataract and microphthalmia), growth retardation, failure to thrive, heart defects, limb anomalies, developmental delay and autism.

About Chromosome 2q24 microdeletion syndrome
Many rare diseases have limited information. Currently GARD aims to provide the following information for this disease:
Population Estimate:Fewer than 1,000 people in the U.S. have this disease.
Symptoms:May start to appear during Pregnancy and as a Newborn.
Cause:This is caused by changes in the way information is arranged into chromosomes.
Organizations:Patient organizations are available to help find a specialist, or advocacy and support for this specific disease.

Chromosome Disorder
Chromosome 2q24 microdeletion syndrome is a chromosome disorder, which means it is caused by changes in the way information is arranged into chromosomes.
What Is a Chromosome?
Chromosomes are thread-like structures found inside the nucleus of human cells. Each chromosome is made of DNA, and DNA is passed from parents to their children.
Humans usually have 46 chromosomes. The first 22 pairs of chromosomes, called autosomes, are found in males and females. The 23rd pair comprises the sex chromosomes. Each parent passes on 22 autosomes and one sex chromosome to their offspring.
The cells in our bodies must constantly divide and produce new cells. Chromosomes play a key role in making sure DNA is copied and passed along during cell division. However, on rare occasions, mistakes do occur. These mistakes can lead to chromosome disorders.

Patient organizations can help patients and families connect. They build public awareness of the disease and are a driving force behind research to improve patients' lives. They may offer online and in-person resources to help people live well with their disease. Many collaborate with medical experts and researchers.
Services of patient organizations differ, but may include:
Ways to connect to others and share personal stories
Easy-to-read information
Up-to-date treatment and research information
Patient registries
Lists of specialists or specialty centers
Financial aid and travel resources

Clinical studies are part of clinical research and at the heart of all medical advances, including rare diseases. Participating in research helps researchers ultimately uncover better ways to treat, prevent, diagnose, and understand human diseases.
What Are Clinical Studies?
Clinical studies are medical research involving people as participants. There are two main types of clinical studies:
Clinical trials determine if a new test or treatment for a disease is effective and safe by comparing groups receiving different tests/treatments.
Observational studies involve recording changes over time among a specific group of people in their natural settings.
People participate in clinical trials for a variety of reasons. Participants with a disease may participate to help others, but also to possibly receive the newest treatment and additional care from clinical study staff. Healthy volunteers may also participate to help others and to contribute to moving science forward.
How Do You Find the Right Clinical Study?
To find the right clinical study we recommend you:
Use ClincalTrials.gov button below to search for studies by disease, terms, or country.
Consult doctors, other trusted medical professionals, and patient organizations.
Enroll in databases to allow researchers from participating institutions to find you.
What if There Are No Available Clinical Studies?
ResearchMatch helps connect people interested in research studies with researchers from top medical centers across the United States. Anyone from the U.S. can register with this free program funded by NIH. Researchers from participating institutions use the database to search for and invite patients or healthy volunteers who meet their study criteria to participate.
