Syndromic ichthyoses.

Area of Science:

• Dermatology
• Medical Genetics
• Rare Diseases

Background:

• Inherited ichthyoses are Mendelian disorders of cornification (MEDOC), classified as syndromic or non-syndromic.
• Mutations in over 30 genes cause syndromic ichthyoses, characterized by skin scaling and hyperkeratosis, plus extra-cutaneous organ involvement.
• Syndromic ichthyoses are rare, classified by inheritance and symptoms.

Purpose of the Study:

• To provide a concise overview of prevalent syndromic ichthyosis subgroups.
• To highlight the importance of clinical assessment alongside genetic testing for diagnosing complex syndromes.
• To emphasize assessing organ involvement for efficient diagnosis, therapy, and reproductive counseling.

Main Methods:

• Review of prevalent syndromic ichthyosis forms.
• Emphasis on clinical assessment and genetic features.
• Discussion of diagnostic and therapeutic approaches.

Main Results:

• Overview of the most common syndromic ichthyosis subgroups.
• Importance of clinical assessment for syndromic ichthyosis diagnosis.
• Need for active assessment of organ involvement.

Conclusions:

• Clinical assessment remains vital for diagnosing complex syndromic ichthyoses, even with genetic testing.
• Early diagnosis of organ involvement guides therapeutic strategies and reproductive options.
• Establishment of specialized centers facilitates patient care for rare cornification disorders.
