Cenani-Lenz Syndactyly Syndrome is a rare congenital disorder characterized by complete or partial fusion of fingers and toes. It is caused by mutations in the LRP4 gene, which disrupts normal limb development during embryonic growth. The MuSK and LRP4 Antibodies Panel is the most important test for assessing LRP4 protein function abnormalities that may lead to genetic confirmation.

Cenani-Lenz Syndactyly Syndrome is caused by mutations in the LRP4 gene, which plays a critical role in limb development during embryonic growth. These genetic mutations disrupt the normal separation of fingers and toes, leading to complete or partial fusion called syndactyly. The LRP4 protein is essential for proper limb formation, and when its function is impaired by genetic changes, it results in the characteristic webbing or fusion of digits seen in this rare congenital disorder.
The MuSK and LRP4 Antibodies Panel is the most important blood test for Cenani-Lenz Syndactyly Syndrome because it detects antibodies against LRP4 protein, which is directly connected to the genetic cause of this condition. This panel helps identify abnormal LRP4 function that may be associated with the underlying genetic mutations. While genetic testing remains the gold standard for definitive diagnosis, the LRP4 antibody testing provides valuable information about protein function abnormalities and can guide healthcare providers toward comprehensive genetic evaluation when clinical presentation suggests this rare syndrome.
You should get tested if your child is born with webbed or fused fingers or toes, especially if multiple digits are affected on both hands and feet. Testing is also recommended if there is a family history of syndactyly or limb malformations, or if prenatal ultrasound reveals limb abnormalities. Early evaluation with blood work assessing LRP4 protein function can help guide genetic counseling and prepare for potential surgical interventions to separate fused digits and improve hand or foot function.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
