Living with Trichomegaly-retina pigmentary degeneration-dwarfism syndrome

An extremely rare genetic condition (Oliver-McFarlane syndrome) with long eyelashes, vision loss from the retina, and short stature.

Understanding Trichomegaly-retina pigmentary degeneration-dwarfism syndrome

Trichomegaly-retina pigmentary degeneration-dwarfism syndrome, also called Oliver-McFarlane syndrome, is an extremely rare genetic condition that affects hair, eyes, and growth.

It involves hair differences, severe damage to the back of the eye (chorioretinal atrophy), low levels of pituitary hormones (hypopituitarism), short stature, and intellectual disability. It is noticed in the newborn period or infancy.

Signs & symptoms

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

  • Long eyelashes (trichomegaly)
  • Retina degeneration and vision problems
  • Short stature and slow growth
  • Intellectual disability
  • Low activity of the sex glands (hypogonadism)
  • Underactive thyroid (hypothyroidism)

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 brain and nervous system specialists, eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

    Changes in PNPLA6 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

    National Foundation for Ectodermal Dysplasias may keep lists of experts for this condition.

InheritanceAutosomal Recessive
GenesPNPLA6

This condition is caused by changes in the PNPLA6 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
