Congenital deafness with labyrinthine aplasia microtia and microdontia is a rare genetic condition that is characterized by the absence of the inner ear structures, hearing loss, and craniofacial abnormalities such as microtia (underdeveloped external ear) and microdontia (small teeth). This syndromic form of deafness is caused by mutations in genes involved in the development of the inner ear and craniofacial structures.

According to the OMIM database, there are several genes associated with this condition, including the fibroblast growth factor 3 (FGF3) gene. These mutations disrupt the normal development of the inner ear, leading to aplasia (absence) of the labyrinthine structures. Other genes involved in this condition include PAX2, SIX1, and EYA1.

The frequency of this condition is not well-documented, as it is considered a rare disease. However, several articles in scientific journals and resources such as PubMed and the National Center for Biotechnology Information (NCBI) provide more information about this condition and the genetic mutations associated with it.

Testing for genetic mutations in these genes can help confirm a diagnosis of congenital deafness with labyrinthine aplasia microtia and microdontia. Additional information and support can be found through patient advocacy groups and resources such as the Genetic and Rare Diseases Information Center (GARD).

In conclusion, congenital deafness with labyrinthine aplasia microtia and microdontia is a rare genetic condition that affects the development of the inner ear and craniofacial structures. Mutations in several genes are known to be associated with this condition, and genetic testing can provide a definitive diagnosis. Further research and information are necessary to understand the causes and inheritance patterns of this condition.

Frequency

Congenital deafness with labyrinthine aplasia microtia and microdontia (LAMM) is a rare genetic condition characterized by hearing loss, labyrinthine aplasia (absence of the inner ear structures), microtia (abnormal development of the external ear), and microdontia (small or absent teeth).

The older you get, the more you will be forced to spend on healthcare. A couple retiring at age 65 in 2018 will spend $280,000, on average, on medical costs throughout their retirement, not counting the expense of over-the-counter medications or the cost of living in a nursing home, CBS News

The exact frequency of LAMM is unknown, as it is a rare condition. However, it has been reported in several cases and is associated with mutations in specific genes. The condition has been found to be inheritable, with both autosomal recessive and dominant inheritance patterns observed.

Causes

The causes of congenital deafness with labyrinthine aplasia microtia and microdontia (LAMM) are not yet fully understood. However, scientific research has identified some factors that may be involved in the development of this condition.

Genetic mutations: Genetic mutations have been found to play a role in the development of LAMM. Mutations in certain genes have been associated with this condition, including the fibroblast growth factor receptor 1 (FGFR1) gene. These mutations can disrupt the normal development of the labyrinth (part of the inner ear), leading to deafness.

Hearing loss genes: Mutations in genes that are involved in the development and function of the auditory system can also cause congenital deafness. These genes play a crucial role in the development of the inner ear structures necessary for hearing, including the cochlea and the auditory nerve.

Inheritance: LAMM can be inherited in an autosomal recessive manner, which means that both copies of the gene must be mutated for the condition to manifest. This type of inheritance pattern suggests that individuals with LAMM have inherited gene mutations from both parents.

Other causes: In some cases, LAMM may be associated with other syndromic conditions that affect the development of multiple organs and tissues in the body. These syndromes can have a wide range of symptoms, including hearing loss, microtia (abnormal ear development), and microdontia (abnormal tooth development).

Testing and diagnosis: Genetic testing can be used to identify mutations in specific genes associated with LAMM. This can help confirm the diagnosis of the condition and provide information about its inheritance pattern. It is important for patients with LAMM and their families to receive appropriate genetic counseling and support.

Support and advocacy: Patients and their families can benefit from resources and support provided by advocacy organizations, such as the National Organization for Rare Disorders (NORD) and the Genetic and Rare Diseases Information Center (GARD). These organizations offer information, patient support, and resources to help individuals and families navigate the challenges of living with a rare genetic condition like LAMM.
