Black panther

Melanism in the jaguar (Panthera onca) is conferred by a dominant allele, and in the leopard (Panthera pardus) by a recessive allele.

Chronic progressive external ophthalmoplegia

Dominant and recessive forms of PEO can be caused by genetic mutations in the ANT1, POLG, POLG2 and PEO1 genes.

COL4A4

Mutations in this gene are associated with type II autosomal recessive Alport syndrome (hereditary glomerulonephropathy) and with familial benign hematuria (thin basement membrane disease).

Congenital myopathy

When the mutation takes place in the BIN1 gene, the disease is instead autosomal recessive, and both genes must be mutated for the disease to be inherited.

D-bifunctional protein deficiency

D-Bifunctional protein deficiency (officially called 17-β-hydroxysteroid dehydrogenase IV deficiency) is an autosomal recessive peroxisomal fatty acid oxidation disorder.

Duchenne

Duchenne muscular dystrophy, a severe recessive X-chromosome linked form of muscular dystrophy

Focal dermal hypoplasia

The differential diagnosis of focal dermal hypoplasia (Goltz) syndrome includes autosomal recessive Setleis syndrome due to TWIST2 gene mutations.

Frank Bassen

In partnership with Abraham Kornzweig, Bassen identified Bassen-Kornzweig disease, a rare autosomal recessive disorder in which the body fails to produce chylomicrons, a low density lipoprotein (LDL) and very low density lipoprotein (VLDL).

Heterozygote advantage

Cystic fibrosis (CF) is an autosomal recessive hereditary disease of the lungs, sweat glands and digestive system.

Homeosis

Homeotic mutants in angiosperms are thought to be rare in the wild: in the annual plant Clarkia, (Onagraceae), homeotic mutants are known where the petals are replaced by a second whorl of sepal like organs, originating via a mutation governed by a single recessive gene.

Joseph Paruta

It is suspected that Joseph suffered from Werner syndrome, a rare autosomal recessive disorder that is characterized by the appearance of premature aging.

Kostmann syndrome

Homozygous mutations in the HAX1 gene are associated with Kostmann disease, i.e. the "classical," autosomal recessive form of severe congenital neutropenia (SCN3).

Lucien Cuénot

Archibald Garrod suggested in the early part of the 20th century that certain diseases occurred in the absence of an essential enzyme in a biochemical pathway and that these diseases were inherited as Mendelian recessives.

Mohr–Tranebjærg syndrome

Mohr–Tranebjærg syndrome (MTS) is a rare X-liked recessive syndrome also known as Deafness-dystonia syndrome and caused by mutation in the TIMM8A gene.

Netherton syndrome

Netherton syndrome is an autosomal recessive disorder associated with mutations in the SPINK5 gene, which encodes the serine protease inhibitor lympho-epithelial Kazal-type-related inhibitor (LEKTI).

Phytanic acid

Individuals with adult Refsum disease, an autosomal recessive neurological disorder caused by mutations in the PHYH gene, have impaired α-oxidation activity and accumulate large stores of phytanic acid in their blood and tissues.

Phytol

Refsum disease, an autosomal recessive disorder that results from the accumulation of large stores of phytanic acid in tissues, frequently manifests peripheral polyneuropathy, cerebellar ataxia, retinitis pigmentosa, anosmia, and hearing loss.

Pitt–Hopkins syndrome

A Pitt–Hopkins like phenotype has been assigned to autosomal recessive mutations of the contactin associated protein like 2 (CNTNAP2) gene on the long arm of chromosome 7 (7q33-q36) and the neurexin 1 alpha (NRXN1) gene on the short arm of chromosome 2 (2p16.3).

Trichorrhexis invaginata

The Netherton syndrome Mendelian Inheritance in Man is inherited as an autosomal recessive disorder due to mutations of both copies of the SPINK5 gene (localized to band 5q31-32), which encodes the serine protease inhibitor LEKTI (lymphoepithelial Kazal-type-related inhibitor).

White lion

The leucistic trait is due to a recessive mutation in the gene for Tyrosinase (TYR), an enzyme responsible for the production of melanins.

WNT1

This gene was originally considered as a candidate gene for Joubert syndrome, an autosomal recessive disorder with cerebellar hypoplasia as a leading feature.
