Living with Taybi-linder syndrome

A rare genetic condition with very short stature, small head, and brain, eye, and hearing differences.

Understanding Taybi-linder syndrome

Taybi-Linder syndrome is a rare genetic condition with short stature, a small head, and nervous system differences.

It involves changes in the RNU4ATAC gene, part of a cell system that helps process genetic messages. People have dwarfism, a small head (microcephaly), and brain differences. Intellectual disability and eye and hearing differences are also described.

Signs & symptoms

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

  • Very short stature
  • Small head (microcephaly)
  • Brain differences
  • Slow growth before birth
  • Intellectual disability
  • Eye and hearing differences

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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

Care & treatment

  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits

Quick facts

InheritanceAutosomal Recessive

Changes in the RNU4ATAC gene cause this condition. It is autosomal recessive, meaning a child inherits a changed copy of the gene from each parent.

Also known as: brachymelic primordial dwarfism; cephaloskeletal dysplasia; low-birth-weight dwarfism with skeletal dysplasia; microcephalic osteodysplastic primordial dwarfism type i; microcephalic osteodysplastic primordial dwarfism type i/iii; microcephalic osteodysplastic primordial dwarfism, caroline crachami type
