HistoryThis section has been translated automatically.

Menkes, 1962

DefinitionThis section has been translated automatically.

X-linked recessive, progressive, neurodegenerative disease due to copper absorption disorders in the intestine and impaired copper transport in tissue. Among other things, this leads to disorders of copper-dependent tyrosinase (depigmentation of hair), increase in free sulfhydryl groups in keratin with consecutive impairment of the disulfide bridges of the keratin molecules (brittleness of hair).

Occurrence/EpidemiologyThis section has been translated automatically.

Incidence: 1:298,000 live births.

EtiopathogenesisThis section has been translated automatically.

X-linked recessive mutations of the ATP7a gene (Cu-transporting ATPase, alpha polypeptide gene; gene locus Xq12-Xq13.3). The defective ATP7a gene codes for a copper-transporting ATPase, which is responsible for the intracellular transport of this trace element (Fujisawa C et al. 2019). Many symptoms of kinky hair disease can be attributed to the reduced activity of 5 copper-dependent enzymes, including lysyl oxidase and tyrosinase.

ManifestationThis section has been translated automatically.

Mostly 5th week of life to 5th month of life. Boys are preferentially infested.

LocalizationThis section has been translated automatically.

Head hair, eyebrows.

Clinical featuresThis section has been translated automatically.

Pale skin with pronounced cutis laxa.

Pili torti, sparse, low-pigment, bristly, lackluster, kinked hair.

Physical and psychomotor retardation, cramps, often hypothermia episodes. Growth disorders with scurvy bone changes. Progressive signs of decerebration. Mask-like face with roundish, drooping cheeks, often a rigid gaze.

Brain: Dilatation of the lateral ventricles, hypoplasia or atrophy of cerebrum and cerebellum, demyelination, leukomalacia, subdural hematomas.

Skeleton: metaphyseal gouging and spur formation, diaphyseal periosteal deposits, switch bones on the skull, osteoporosis, rarely platyspondylia.

Vessels: Tortuosity, dilatation (jump in calibre) and/or proliferation as well as corkscrew-like torsion of the intracranial and visceral arteries; bladder diverticula, vesicoureteral reflux.

LaboratoryThis section has been translated automatically.

Pathologically deep serum copper and coeruloplasmin, abnormally increased copper uptake by cultured fibroblasts

DiagnosisThis section has been translated automatically.

Prenatal diagnosis from chorionic villi is more reliable than from amniotic fluid cells.

Chorionic villi: copper content increased (several times the norm), copper bound to trophoblast cell membrane is detectable by electron microscopy.

Amniotic fluid cells: increased copper absorption.

TherapyThis section has been translated automatically.

Under copper substitution (copper histidinate) improvement of hair structure and pigmentation are described. This cannot improve the prognosis.

Progression/forecastThis section has been translated automatically.

The course is determined by cramping and airway infections (immobilization, aspiration). Death in infancy or toddlers, mostly in the 4th to 5th year of life. Very rarely survival into adulthood is described.

Note(s)This section has been translated automatically.

The Ocipital horn syndrome has been known in the past as"cutis-laxa". However, it has the same genetic defect as the Menkes syndrome (Kinky hair disease), so that it can be classified as a negative variant of this syndrome.
