The 19 pages that link to Variable expressivity, each with the reason it gives.

• Autosomal dominant inheritanceRelated: Carriers of the same dominant variant can have markedly different symptoms.

• PenetranceCompared with: It concerns differences in phenotype among affected individuals, not whether the phenotype appears.

• Genotype–phenotype correlationRelated: It describes differences in severity that a simple genotype-to-disease link misses.

• De novo mutationRelated: Even when a new variant causes disease, its effects can differ substantially between individuals.

• HaploinsufficiencyRelated: Different outcomes among carriers can reflect modifiers of a shared dosage deficit.

• Pedigree chartRelated: Relatives carrying the same variant may show markedly different symptoms.

• 22q11.2 deletion syndromeRelated: People with the same deletion can have markedly different clinical features.

• Medical geneticsRelated: It explains why one inherited condition can look different within a family.

• Alagille syndromeRelated: People with the same syndrome-causing variant can have markedly different organ findings.

• Hereditary spastic paraplegiaRelated: Even within one family, age of onset and disability can differ substantially.

• Dominant traitRelated: People carrying a dominant allele may show different levels or features of its effect.

• EctrodactylyRelated: Affected relatives can have markedly different hand or foot involvement.

• Barth syndromeRelated: People with Barth syndrome can differ substantially in symptoms and clinical course.

• Cornelia de Lange syndromeRelated: The syndrome ranges from severe, recognizable presentations to milder forms.
