Symptoms and Clinical Presentation
Individuals with McKusick–Kaufman syndrome may present with a range of symptoms that can affect different parts of the body. One common feature is the presence of hydrometrocolpos, a condition where fluid accumulates in the vagina due to blockage or malformation of the genital tract. This can lead to abdominal distention, pelvic pain, and potentially serious complications if not addressed promptly.
Hydrometra, which involves the abnormal accumulation of fluid in the uterus, is another common feature of McKusick–Kaufman syndrome. This can cause pelvic or abdominal discomfort and may require medical intervention to alleviate symptoms and prevent complications.
Polydactyly, a condition characterized by the presence of extra fingers or toes, is also frequently observed in individuals with McKusick–Kaufman syndrome. While polydactyly may not always cause significant functional impairment, surgical intervention may be considered for cosmetic or functional reasons.
Heart defects are another important aspect of McKusick–Kaufman syndrome. These defects can vary in severity and may affect the structure and function of the heart, leading to symptoms such as fatigue, shortness of breath, or poor growth in affected individuals. Close monitoring by a cardiologist is often necessary to manage heart-related issues effectively.
Short stature is a common feature of McKusick–Kaufman syndrome, where affected individuals may have a height below the average range for their age and gender. Growth hormone therapy and other interventions may be recommended to support optimal growth and development in these individuals.
Renal abnormalities, such as structural defects or impaired kidney function, are also seen in McKusick–Kaufman syndrome. These abnormalities may manifest as urinary tract infections, kidney stones, or other complications that require monitoring and appropriate management by a nephrologist.
The diverse array of symptoms associated with McKusick–Kaufman syndrome underscores the need for a comprehensive approach to diagnosis and management, involving healthcare providers from multiple specialties to address the complex needs of affected individuals effectively.

Genetic Basis
McKusick–Kaufman syndrome is classified as an autosomal recessive disorder, meaning that both copies of the responsible gene must be mutated for an individual to develop the condition. The genetic basis of McKusick–Kaufman syndrome is linked to mutations in the MKKS gene, also known as the BBS6 gene.
The MKKS gene provides instructions for producing a protein that plays a crucial role in the development and function of cilia, which are hair-like structures found on the surface of cells. Cilia have essential functions in cell signaling, sensory perception, and fluid movement in various tissues and organs throughout the body.
When mutations occur in the MKKS gene, the normal structure and function of cilia are disrupted, leading to the diverse range of symptoms observed in McKusick–Kaufman syndrome. These abnormalities in cilia function can affect multiple organ systems, contributing to the complex clinical manifestations of the syndrome.
Individuals who inherit two mutated copies of the MKKS gene from their parents are at risk of developing McKusick–Kaufman syndrome. Carriers of a single mutated copy of the gene are typically unaffected but can pass the mutation on to their offspring. Genetic testing plays a crucial role in identifying carriers of the mutation and enabling informed family planning decisions.
Understanding the genetic basis of McKusick–Kaufman syndrome is essential for accurate diagnosis, genetic counseling, and ongoing research efforts aimed at developing targeted therapies for individuals affected by this rare genetic disorder. Advances in genetic testing technologies continue to improve our ability to identify genetic mutations associated with McKusick–Kaufman syndrome and other ciliopathies, facilitating personalized approaches to patient care.
