Causes of Short Limb Dwarf Lethal Mcalister–Crane Type

Short limb dwarf lethal Mcalister–Crane type is primarily caused by a genetic mutation affecting skeletal development.

  • Genetic mutation
  • Defect in bone development
  • Inadequate growth of limbs
  • Abnormal skeletal structure

Types of Short Limb Dwarf Lethal Mcalister–Crane Type

Short limb dwarf lethal Mcalister–Crane type can present with varying manifestations affecting different parts of the body, leading to a range of physical and developmental challenges.

  • Short limb dwarf lethal Mcalister–Crane type 1: Characterized by severe skeletal abnormalities and shortened limbs, leading to lethal outcomes shortly after birth.
  • Short limb dwarf lethal Mcalister–Crane type 2: Presents with distinct facial features, joint dislocations, and respiratory issues, often resulting in early mortality.
  • Short limb dwarf lethal Mcalister–Crane type 3: Manifests with short stature, clubbed feet, and underdeveloped lungs, causing lifethreatening breathing difficulties in affected individuals.
  • Short limb dwarf lethal Mcalister–Crane type 4: Features include short limbs, a narrow chest, and heart defects, contributing to the lethal nature of the condition.
  • Short limb dwarf lethal Mcalister–Crane type 5: Exhibits severe limb shortening, abnormal spinal curvature, and craniofacial anomalies, leading to a lethal outcome shortly after birth.

Risk Factors

Short limb dwarf lethal McAlister–Crane type is a genetic disorder caused by mutations in the SLC26A2 gene, leading to abnormal bone development and short stature.

  • Genetic mutations
  • Inherited condition
  • Family history of the disorder
