Living with Lowry-Wood syndrome

A very rare inherited condition with short height, a small head, bone differences at the ends of long bones, and some learning delay.

Understanding Lowry-Wood syndrome

Lowry-Wood syndrome is a rare condition with epiphyseal dysplasia (changes at the ends of long bones), short stature, and a small head.

In the first reported cases, babies also had congenital nystagmus (involuntary eye movements). Fewer than 10 cases have been described. Intellectual disability of varying degrees has been reported. Occasional features include retinitis pigmentosa and coxa vara (a hip bone angle difference).

Signs & symptoms

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

  • Changes at the ends of long bones (epiphyseal dysplasia)
  • Small head (microcephaly)
  • Intellectual disability
  • Involuntary eye movements (nystagmus)
  • Hip bone angle difference (coxa vara)
  • Retina pigment changes

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 bone and joint specialists and genetic specialists.

  3. Consider genetic testing

    Changes in RNU4ATAC are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Everyday life

Living with a rare condition is easier with support.

  • Connect with rare disease patient organizations for support
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits

Quick facts

InheritanceAutosomal Recessive
GenesRNU4ATAC

It is caused by changes in the RNU4ATAC gene. A child inherits a changed copy of the gene from each parent (autosomal recessive).
