The oro-facial-digital syndrome

Area of Science:

• Genetics
• Medical Genetics
• Syndromology

Background:

• Oro-facial-digital syndrome (OFD I) and Mohr syndrome (OFD II) are distinct genetic disorders with overlapping clinical manifestations.
• Diagnostic confusion arises when patients present with features common to both syndromes.
• Understanding the precise classification and spectrum of these syndromes is crucial for accurate diagnosis and management.

Observation:

• Two patients, a mother and daughter, presented with clinical features consistent with OFD I.
• Many observed features were also characteristic of OFD II, highlighting significant overlap.
• Additional, previously unclassified, clinical and radiological abnormalities were noted in the patients.

Findings:

• A comprehensive tabulation of features associated with OFD I and OFD II revealed substantial commonality.
• The presented cases suggest that OFD I and OFD II may represent a single, broader syndrome.
• The proposed expanded syndrome includes ear and renal abnormalities, alongside the typical oro-facial digital features.

Implications:

• Consolidating OFD I and OFD II into a single syndrome could simplify diagnosis and reduce clinical uncertainty.
• Expanding the syndrome's definition may improve recognition and management of associated anomalies, such as ear and renal issues.
• Further research is needed to clarify the genetic basis and precise boundaries of this proposed unified syndrome.
