The 70 pages that link to Autosomal recessive inheritance, each with the reason it gives.

• Genetic counselingRelated: This pattern frames carrier results and reproductive risk discussions.

• Autosomal dominant inheritanceCompared with: It usually requires two altered copies, unlike the one-copy threshold of dominant inheritance.

• Newborn screeningRelated: Many screened genetic disorders follow this inheritance pattern.

• Cystic fibrosisNarrower topic: Cystic fibrosis usually develops when both inherited CFTR copies carry disease-causing variants.

• Sickle cell diseaseRelated: Most forms require disease-associated globin variants from both parents.

• X-linked inheritanceCompared with: Its two-copy requirement differs from recessive X-linked disease in people with one X chromosome.

• Retinitis pigmentosaRelated: Many affected people have no family history because relatives may carry one variant.

• Carrier screeningBroader topic: Most carrier screening targets variants that can cause disease when inherited from both parents.

• X-linked recessive inheritanceCompared with: Unlike X-linked recessive inheritance, it affects males and females at similar rates.

• Genetic disorderRelated: Carriers can pass on an altered gene without having the disorder themselves.

• Pedigree chartBroader topic: Unaffected parents can have an affected child, a recurring pedigree clue.

• Wilson's diseaseRelated: Wilson's disease usually develops when pathogenic ATP7B variants are inherited from both parents.

• Spinal muscular atrophyRelated: Most common spinal muscular atrophy results from inheriting affected SMN1 copies from both parents.

• LeukodystrophyRelated: Many leukodystrophies follow this inheritance pattern, though other patterns also occur.

• Hereditary spherocytosisCompared with: Some severe cases follow recessive inheritance rather than the more common dominant pattern.

• Alport syndromeRelated: Biallelic COL4A3 or COL4A4 variants can cause severe Alport syndrome.

• Congenital myopathyRelated: Many congenital myopathies occur when both gene copies are affected.

• Gaucher diseaseRelated: Gaucher disease typically requires pathogenic variants in both GBA1 copies.

• Chronic granulomatous diseaseCompared with: Several forms follow this pattern rather than the more common X-linked pattern.

• Ataxia–telangiectasiaNarrower topic: Ataxia–telangiectasia generally requires pathogenic ATM variants inherited from both parents.

• Bardet–Biedl syndromeRelated: Most cases arise when a person inherits an altered BBS gene copy from each parent.

• Crigler–Najjar syndromeRelated: Crigler–Najjar syndrome typically develops when both UGT1A1 copies carry pathogenic variants.

• CystinuriaRelated: This pattern commonly describes cystinuria caused by SLC3A1 variants.

• Tay–Sachs diseaseRelated: Tay–Sachs disease typically develops when a person inherits pathogenic HEXA variants from both parents.

• X-linked dominant inheritanceCompared with: Its two-copy requirement contrasts with the one-copy effect described by X-linked dominant inheritance.

• CystinosisNarrower topic: Cystinosis usually develops when a person inherits a disease-causing CTNS variant from each parent.

• Dubin–Johnson syndromeBroader topic: This explains why carriers are generally unaffected and the disorder may appear among siblings.

• Krabbe diseaseRelated: Krabbe disease is usually inherited when a child receives a nonworking GALC copy from each parent.

• Leber congenital amaurosisRelated: Most cases result from pathogenic variants inherited in two copies of a gene.

• Maple syrup urine diseaseRelated: Affected children typically inherit one disease-causing variant from each carrier parent.

• Metachromatic leukodystrophyNarrower topic: Most cases arise when both inherited copies of ARSA or PSAP are affected.

• Xeroderma pigmentosumRelated: Most XP forms follow this pattern, shaping recurrence risks within families.

• Bloom syndromeRelated: Bloom syndrome usually requires a disease-causing BLM variant from each parent.

• Canavan diseaseRelated: Canavan disease generally requires pathogenic ASPA variants from both parents.

• Charcot–Marie–Tooth diseaseRelated: Some CMT forms appear when a person inherits disease-causing variants from both parents.

• Cockayne syndromeRelated: Cockayne syndrome generally requires disease-causing variants in both copies of an associated gene.

• Fanconi anemiaRelated: Most Fanconi anemia forms follow this inheritance pattern.

• GalactosemiaRelated: Most forms of galactosemia follow this pattern, giving carrier parents a 25% recurrence risk per pregnancy.

• Gitelman syndromeRelated: Gitelman syndrome typically requires pathogenic variants in both copies of SLC12A3.

• Hartnup diseaseBroader topic: This inheritance pattern accounts for disease in individuals with two affected SLC6A19 copies.

• Leigh syndromeRelated: Many nuclear-gene forms of Leigh syndrome follow this inheritance pattern.

• Rotor syndromeRelated: Rotor syndrome requires pathogenic changes affecting both transporter genes.

• Usher syndromeNarrower topic: Most Usher syndrome forms follow this inheritance pattern.

• AlkaptonuriaRelated: Alkaptonuria typically develops when pathogenic HGD variants are inherited from both parents.

• Alström syndromeRelated: Alström syndrome usually occurs when a child inherits one altered ALMS1 copy from each parent.

• HeterozygousRelated: Heterozygotes often carry one pathogenic variant without having the recessive condition.

• Joubert syndromeRelated: Most Joubert syndrome cases result from two disease-causing variants in a single gene.

• TrimethylaminuriaRelated: The inherited form commonly appears when both FMO3 gene copies are impaired.
