Living with Microcephaly-brachydactyly-kyphoscoliosis syndrome

A very rare inherited syndrome with a small head, short stature, short fingers, a curved spine, and profound intellectual disability.

Understanding Microcephaly-brachydactyly-kyphoscoliosis syndrome

Microcephaly-brachydactyly-kyphoscoliosis syndrome is a very rare inherited syndrome that includes a small head, short fingers and toes, and a curved spine.

People with this syndrome have profound intellectual disability, a small head (microcephaly), and short stature. Other features include short, broad fingers and toes (brachydactyly), certain facial features, and a spine that curves forward and sideways (kyphoscoliosis). GARD says it has been described in three sisters, and signs appear in the newborn period or infancy.

Signs & symptoms

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

  • Smaller-than-average head size (microcephaly)
  • Profound intellectual disability
  • Short stature
  • Curved spine (kyphoscoliosis)
  • Clouding of the eye lens (cataract)
  • Shuffling walk

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, brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Ask which tests can help

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

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
Bring these questions to your next doctor visit
Is genetic testing available to confirm this diagnosis?
How can the curve in the spine be monitored and cared for?
Should my child have regular eye exams because of the cataracts?

Quick facts

Symptoms usually startNewborn and as an Infant
InheritanceAutosomal Recessive

Changes in genes (also called variants) cause this syndrome, and it is likely inherited in an autosomal recessive way. This means a child inherits a changed copy of the gene from each parent.
