Living with Schneckenbecken dysplasia

A rare genetic bone condition identified before birth that affects the pelvis, spine, ribs, and limbs.

Understanding Schneckenbecken dysplasia

Schneckenbecken dysplasia is a rare genetic bone condition, also called chondrodysplasia with snail-like pelvis.

It is a type of spondylodysplastic dysplasia, meaning it affects the spine and other bones. It is noticed during pregnancy. Bone differences include a snail-shaped pelvis, short ribs, and short limbs.

Signs & symptoms

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

  • Short ribs and narrow chest
  • Short limbs
  • Underdeveloped back bones
  • Small pelvic bones (hypoplastic ilia)
  • Large head size
  • Extra amniotic fluid in pregnancy (polyhydramnios)

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 SLC35D1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

Quick facts

Symptoms usually startduring Pregnancy
InheritanceAutosomal Recessive
GenesSLC35D1

It is caused by changes in the SLC35D1 gene. It is autosomal recessive, so a child inherits a changed copy of the gene from each parent.
