Overview

Melhem-Fahl syndrome is a very rare condition that affects the development of the spine, specifically causing abnormal curves or malformations of the vertebrae (the bones that make up the backbone). It belongs to a group of conditions called congenital scoliosis or vertebral segmentation defects, meaning the spine does not form correctly before birth. The backbone may have fused vertebrae, missing vertebrae, or vertebrae that are shaped incorrectly, which can cause the spine to curve sideways or in other unusual directions. People with Melhem-Fahl syndrome may notice a visible curve or twist in their back, uneven shoulders or hips, and sometimes back pain. Because the spine is close to the spinal cord and nerves, some individuals may also experience nerve-related symptoms if the abnormal bones press on nearby structures. The condition is present from birth, though it may not always be noticed right away. Treatment focuses on managing the spinal abnormality and preventing it from getting worse. Options range from careful monitoring and physical therapy to bracing or surgery, depending on how severe the curvature is. A team of specialists including orthopedic surgeons and geneticists typically guides care. There is currently no cure, but many people with this condition can live full lives with appropriate support and treatment.

Key symptoms:

Abnormal curvature of the spine (scoliosis) present from birthFused or malformed vertebrae (backbone bones)Uneven shoulders or hipsVisible hump or twist in the backBack pain or stiffnessReduced flexibility of the spinePossible nerve-related symptoms such as weakness or numbness in the limbs if the spinal cord is affectedShortened trunk or uneven body proportions

Inheritance

Autosomal dominant

Passed on from just one parent; each child has about a 50% chance of inheriting it

Age of Onset

Neonatal

Begins at or shortly after birth (first 4 weeks)
