3-M syndrome, also known as Three M syndrome, is a rare genetic condition that affects growth and development. The name “3-M” refers to the three main signs of the syndrome:

• Short stature (including shortened arms and legs)
• Prominent round face with a pointed chin
• Mesomelic limb shortening (curvature of the limbs)

This genetic disorder was first described in 1974 and is thought to be inherited in an autosomal recessive manner. The syndrome has been associated with mutations in the CUL7, OBSL1, and CCDC8 genes among others. These genes are involved in the ubiquitin-proteasome pathway, which plays a critical role in protein degradation.

OMIM (Online Mendelian Inheritance in Man) and other scientific resources provide additional information and support for patients and their families. The OMIM database contains detailed information on the genetics, clinical features, and inheritance patterns of diseases, including 3-M syndrome. The Center for Genetic Testing (Cormier-Daire and Clayton) offers genetic testing for this condition.

More information about 3-M syndrome can be found in scientific articles published in journals such as the American Journal of Medical Genetics and the American Journal of Medical Genetics Part A. PubMed, a database of biomedical literature, also contains numerous articles on this topic.

Advocacy and support groups such as the 3-M Syndrome Support Group are available to provide information, resources, and a community for individuals and families affected by this rare condition. These groups often collaborate with medical professionals and researchers to learn more about the syndrome and improve patient outcomes.

“3-M syndrome is a rare condition with a narrow face, narrow shoulders, prominent round face, and a pointed chin.” – Yakut et al., 2010

Once you do get to see the doctor, don’t be surprised if you’re rushed out of the exam room before you get all of your questions answered, according to healthcare staffing agency Staff Care. Studies show that 41% of ophthalmologists spend just 9 to 12 minutes with a patient, and 13- to 16-minute appointments are the norm for 40% of cardiologists, 37% of pediatricians, 35% of urologists, 35% of family physicians, 34% of obstetricians and gynecologists and 30% of otolaryngologists.

In conclusion, 3-M syndrome is a rare genetic condition that affects growth and development. It is caused by mutations in several genes involved in the ubiquitin-proteasome pathway. OMIM and other scientific resources provide valuable information and support for affected individuals and their families. Genetic testing is available for a definitive diagnosis, and advocacy and support groups offer additional resources and community for those affected by this condition.

Frequency

3-M syndrome is a rare genetic condition. It is believed to have a frequency of approximately 1 in 100,000 to 1 in 200,000 individuals worldwide. This estimate is based on the limited number of reported cases in the scientific literature and in databases such as OMIM (Online Mendelian Inheritance in Man) and PubMed.

The full name of the condition is 3-M syndrome, which stands for “mid-trimester miscarriage, microcephaly (small head size), metaphyseal dysplasia (abnormal bone development),” the main features associated with this condition. However, there are some variations in the features observed in individuals with 3-M syndrome, and additional genes have been associated with the condition.

Currently, mutations in three genes are thought to be associated with 3-M syndrome: CUL7 (cullin-7), OBSL1 (obscurin-like 1), and CCDC8 (coiled-coil domain-containing protein 8). These genes play a role in a pathway known as the ubiquitin-proteasome system, which is involved in protein degradation within the body. Mutations in these genes are thought to disrupt this pathway, leading to the characteristic features of 3-M syndrome.

The inheritance pattern of 3-M syndrome is autosomal recessive, meaning that individuals with the condition have inherited two copies of the mutated gene, one from each parent. However, there is still much to learn about the genetics of 3-M syndrome, and additional genes may be identified in the future.

The exact frequency of 3-M syndrome in different populations and regions is not well documented. However, there have been reports of the condition in various populations, including a rare occurrence in the Yakut population of Eastern Siberia. This suggests that 3-M syndrome is not limited to specific ethnic groups or geographic regions.

More information on 3-M syndrome can be found from various resources, including advocacy organizations and scientific articles. Clinicians and researchers interested in this condition can refer to the OMIM catalog, PubMed, and other databases for additional information and references.

It is important to note that 3-M syndrome can often be misdiagnosed or overlooked due to its rarity and overlap with other genetic conditions. Therefore, genetic testing and clinical evaluation by healthcare professionals with expertise in dysmorphology (the study of abnormal physical features) is crucial for accurate diagnosis and appropriate management of individuals with suspected 3-M syndrome.

Causes

The causes of 3-M syndrome are often genetic, with mutations in certain genes thought to be responsible for the condition. According to research articles on Pubmed and OMIM, the genes associated with 3-M syndrome include CUL7 and OBSL1. These genes play a role in the ubiquitin-proteasome pathway, which is involved in protein degradation.

According to articles in the Journal of Medical Genetics by Cormier-Daire et al., mutations in the CUL7 gene are the most common cause of 3-M syndrome. The protein produced by the CUL7 gene is involved in the regulation of cell growth and division. When this protein is not functioning properly, it can lead to the characteristic features of 3-M syndrome, such as short stature, curvature of the spine, and facial dysmorphology.

Inheritance of 3-M syndrome is thought to be autosomal recessive, meaning that both parents must carry a mutation in the same gene in order for their child to develop the condition. However, in some cases, the condition can also occur sporadically, meaning that there is no family history of the syndrome.

For additional information about the genes associated with 3-M syndrome, the patient advocacy group the 3-M Syndrome Support and Advocacy Center provides resources and references to scientific articles on their website. This organization also offers support and information for families affected by 3-M syndrome.

Testing for mutations in the CUL7 and OBSL1 genes is available through certain genetic testing centers. The frequency of these mutations in the general population is not currently known. However, a study conducted in the Yakut population of Siberia found a higher frequency of CUL7 mutations in individuals with short stature and other related skeletal abnormalities.

Inheritance

3-M syndrome is a rare genetic condition that is inherited in an autosomal recessive manner. This means that an individual must inherit two copies of an abnormal gene to develop the syndrome. The genes associated with 3-M syndrome are CUL7, OBSL1, and CCDC8, which are all involved in the ubiquitin-proteasome pathway.

Ubiquitin is a small protein that helps regulate the degradation of other proteins in the body. In individuals with 3-M syndrome, mutations in the CUL7 gene disrupt the normal function of the Cullin-7 protein, which is part of the ubiquitin ligase complex. This disruption leads to abnormal protein degradation and contributes to the development of the syndrome.

The inheritance of 3-M syndrome can be traced back to specific populations and regions around the world. For example, the Yakut population in Siberia has a higher frequency of the condition compared to other populations. In these populations, the syndrome is often referred to by different names, such as “Cormier-Daire syndrome” or “Hanson syndrome”.

Information about the inheritance and causes of 3-M syndrome can be found in scientific articles and databases such as PubMed and OMIM. These resources provide detailed information about the genes associated with the syndrome and the genetic mutations that can cause the condition.

In terms of clinical features, individuals with 3-M syndrome often have characteristic physical traits, such as short stature, facial dysmorphology, and curvature of the spine. However, the severity and specific features can vary among affected individuals.

Genetic testing can be done to confirm a diagnosis of 3-M syndrome. This testing involves analyzing the CUL7, OBSL1, and CCDC8 genes for mutations. Genetic counselors and dysmorphologists can provide additional information and support for patients and families affected by 3-M syndrome.

The 3-M Syndrome Support and Advocacy Group is a resource center for individuals with 3-M syndrome and their families. They provide information and resources about the syndrome, as well as support for affected individuals and their families.

In conclusion, 3-M syndrome is a rare genetic condition inherited in an autosomal recessive manner.
