Living with Cutis laxa - Marfanoid syndrome

A rare genetic condition with loose skin in newborns, a tall slender build with long fingers, and lung and heart differences.

Understanding Cutis laxa - Marfanoid syndrome

Cutis laxa-Marfanoid syndrome is a rare genetic connective tissue syndrome with loose skin in newborns and a Marfan-like body build.

Features include loose skin from birth, long slender fingers (arachnodactyly), emphysema, heart differences, and a hernia in the diaphragm. Mild joint tightness in the elbows, hips, and knees, and hip dislocation on both sides may also occur. It starts in newborns and infants.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Loose, redundant skin
  • Long slender fingers (arachnodactyly)
  • Emphysema
  • Hernia in the diaphragm
  • Hip dislocation
  • Joint tightness (contractures)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include autoimmune and inflammatory disease specialists, bone and joint specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
