It is important for individuals with Miller syndrome and their families to seek support from organizations like the Miller Syndrome Information Center to ensure they have access to the latest information and advancements in research and medical care for this condition.

Frequency

The Miller syndrome is a rare genetic condition that is associated with defects in the DHODH gene. It is estimated to occur in about 1 in 1 million individuals.

Research studies have identified mutations in the DHODH gene as the cause of Miller syndrome. These mutations can result in the production of a non-functional enzyme, leading to the development of various characteristic features of the syndrome.

Miller syndrome is inherited in an autosomal recessive manner, which means that both copies of the gene must be mutated for the condition to manifest. Individuals who have one mutated copy of the gene are carriers of the syndrome, but do not typically show symptoms.

The frequency of Miller syndrome may vary between different populations. Testing for genetic mutations in the DHODH gene can be performed to confirm a diagnosis. More information about testing and resources for patients and families can be found at clinicaltrials.gov.

Additional information about the Miller syndrome, including clinical features, inheritance patterns, and gene names, can be found in the Online Mendelian Inheritance in Man (OMIM) catalog. The OMIM catalog is a database that provides comprehensive information about genetic diseases and the genes associated with them.

The Miller Syndrome Center at the Genee-Wiedemann Rare Disease Advocacy and Research Center provides support and resources for individuals and families affected by this condition.

Causes

Miller syndrome is a rare genetic condition caused by defects in the DHODH gene. This gene provides instructions for making an enzyme called dihydroorotate dehydrogenase (DHODH), which is involved in the production of pyrimidines, a type of molecule that is a building block of DNA.

In Miller syndrome, mutations in the DHODH gene result in a loss or reduction in the activity of the DHODH enzyme. This leads to abnormalities in the development of various body parts, particularly the facial features and limbs.

The inheritance pattern of Miller syndrome is autosomal recessive, meaning that both copies of the DHODH gene must be mutated for the condition to develop. Individuals who inherit one mutated copy of the gene are carriers and do not typically show any symptoms of the syndrome.

The frequency of Miller syndrome is currently unknown, but it is considered to be a rare condition. Only a few dozen cases have been reported in the medical literature.

Diagnosis of Miller syndrome can be confirmed through genetic testing, which analyzes the DHODH gene for mutations. Additional testing, such as clinical evaluation and imaging studies, may also be used to support the diagnosis.

Research on Miller syndrome is ongoing, with several studies and clinical trials registered on websites such as ClinicalTrials.gov. These efforts aim to improve understanding of the condition and explore potential treatment options.

For more information about Miller syndrome, including names of other associated genes and conditions, resources for patient advocacy, and scientific articles on the topic, references and catalogs such as PubMed and the GeneReviews website can be a valuable source of information.
