Living with Cutis laxa with osteodystrophy

A genetic form of cutis laxa (type II) with wrinkled skin, delayed development, and brain and bone differences.

Understanding Cutis laxa with osteodystrophy

Cutis laxa with osteodystrophy is an autosomal recessive form of cutis laxa (type II, classic) caused by changes in the ATP6V0A2 gene.

It is present from birth. People have excess wrinkled skin, loose joints, late-closing skull soft spots, hernias, and slow growth after birth. They can also have global developmental delay, intellectual disability, seizures, and differences in the brain such as in the cerebellum.

Signs & symptoms

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

  • Wrinkled, loose skin
  • Very flexible joints
  • Late-closing skull soft spots
  • Global developmental delay
  • Seizures
  • Slow growth after birth

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, brain and nervous system specialists and digestive system specialists.

  3. Consider genetic testing

    Changes in ATP6V0A2 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Epilepsy Foundation may keep lists of experts for this condition.

Quick facts

InheritanceAutosomal Recessive
GenesATP6V0A2

It is caused by changes in both copies of the ATP6V0A2 gene on chromosome 12q24. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.
