A recent study conducted by researchers from the CHAMP1 Family Foundation and published in the journal Human Genetics has shed light on a genetic condition known as CHAMP1 disorder. This disorder is caused by specific changes, or mutations, in a gene called CHAMP1. People with CHAMP1 disorder often experience problems with learning, and physical abilities, and have distinct physical features. However, there are different types of mutations that can cause this disorder. Scientists wanted to understand if these mutations lead to different effects on people’s health.

Genetic Mutations


According to the research published in the journal Human Genetics by Tess Levy et al. (2023), researchers studied a group of 24 individuals with CHAMP1 disorder. Some had specific mutations in the CHAMP1 gene, while others had larger missing pieces of the gene. The scientists looked at how well these individuals performed in different areas, such as communication skills, daily living abilities, social skills, and physical abilities. They compared the results between the two groups to see if there were any significant differences.


The study revealed some important differences between the two groups. Individuals with specific CHAMP1 mutations had more difficulties in all areas of functioning compared to those with missing pieces of the gene. They had more trouble with speaking, taking care of themselves, interacting with others, and performing physical tasks. They also experienced delays in reaching important developmental milestones, such as sitting, crawling, walking, and speaking their first words.


The findings suggest that the specific mutations in the CHAMP1 gene may have a more severe impact on a person’s health compared to the missing pieces of the gene. It is believed that these mutations may disrupt the normal functioning of the gene, leading to more significant problems in brain development. On the other hand, the missing pieces of the gene may cause fewer issues because there is still some functioning CHAMP1 gene left.

Understanding these differences is crucial for developing treatments for CHAMP1 disorder. Researchers need to know exactly how the mutations affect the gene in order to design effective therapies. The study by Levy provides valuable insights into the distinct effects of specific mutations and deletions on the clinical presentation of CHAMP1 disorder.


In summary, the study highlights the differences between specific mutations and missing pieces of the CHAMP1 gene in individuals with CHAMP1 disorder. It shows that specific mutations can lead to more severe problems with learning, physical abilities, and social interactions. Further research is needed to explore these differences in more detail and develop better treatments for individuals affected by CHAMP1 disorder.
