Wiedemann-Steiner syndrome: three further cases

Area of Science:

• Genetics
• Pediatrics
• Clinical Medicine

Background:

• Wiedemann-Steiner syndrome (WSS) is a rare genetic disorder characterized by specific facial anomalies and developmental delays.
• Previous descriptions of WSS have varied, necessitating further case studies for precise phenotypical delineation.

Observation:

• Three pediatric patients presented with a distinct set of features including arched, thick eyebrows, hypertelorism, and narrow palpebral fissures.
• Additional observed characteristics included a broad nasal bridge and tip, long philtrum, thin upper lip, stubby extremities, hirsutism, and severe psychomotor retardation.

Findings:

• The presented cases expand the known phenotypic spectrum of Wiedemann-Steiner syndrome.
• These findings contribute to a more comprehensive understanding and clearer definition of WSS as a distinct clinical entity.

Implications:

• This expanded phenotype aids clinicians in diagnosing Wiedemann-Steiner syndrome more accurately.
• Further research into the genetic underpinnings and long-term outcomes of WSS is warranted based on these observations.
