ciliary dyskinesia, primary, 51

Ciliary dyskinesia, primary, 51 is a genetic condition that affects the function of motile cilia, leading to respiratory complications and issues with sperm motility. The condition is caused by changes in the BRWD1 gene and follows an autosomal recessive inheritance pattern, meaning both copies of the gene must be affected for the disease to manifest. It typically presents with chronic respiratory symptoms and male infertility, with onset often noted as recurrent infections in early life. Precise prevalence estimates are not well established for this condition.

Individuals with ciliary dyskinesia, primary, 51 frequently exhibit respiratory symptoms such as bronchiectasis, productive cough, chronic rhinitis, and recurrent sinusitis, as well as recurrent respiratory infections. In addition, a number of distinctive reproductive abnormalities are seen in affected males, including short or absent sperm flagella, reduced sperm motility (including reduced progressive motility), irregularly shaped sperm tails, and oligozoospermia. Some patients may also show decreased nasal nitric oxide levels and, in a subset of cases, situs inversus totalis. Not all individuals experience all features, and severity varies considerably.

This condition is caused by pathogenic variants in the BRWD1 gene. The BRWD1 protein plays a role in cellular function, and disruption of its normal activity contributes to the impaired structure or function of cilia. Ciliary dyskinesia, primary, 51 is inherited in an autosomal recessive pattern, meaning that an affected individual has inherited a mutated copy of the gene from each parent. Families are advised to consider genetic counseling, since when both parents are carriers there is a 25% chance with each pregnancy for the condition to occur.

Currently, management of ciliary dyskinesia, primary, 51 focuses on supportive care and symptom management. Although there are no specific FDA-approved treatments for this condition, a multidisciplinary team approach is typically employed to address chronic respiratory issues and reproductive challenges. Regular surveillance, such as monitoring for respiratory complications, plays an important role in long-term care. Patients are encouraged to discuss potential management strategies and supportive therapies with their healthcare team, and genetic counseling may provide additional guidance regarding family planning.

The outlook for individuals with ciliary dyskinesia, primary, 51 can vary widely, with some patients experiencing a relatively stable course while others may have more frequent respiratory complications. With current standards of care, many individuals are able to manage their symptoms effectively, though the severity of respiratory and reproductive manifestations differs from person to person. Outcomes described in medical literature continue to evolve as standards of care improve. Families are encouraged to connect with specialists experienced in managing this condition and to consider genetic counseling for insights into future care and family planning options.
