Two patients with Menkes' kinky hair disease were examined. Both showed the characteristic clinical features of this disease in combination with a low plasma-copper level. However, for one of them, studies with 64Cu provided clues that the copper was handled in a way unusual for a Menkes patient, viz., incorporation of 64Cu into ceruloplasmin during an oral 64Cu-loading test and abnormal behavior of skin fibroblasts in in vitro experiments. A comparison with brindled mice and some clinical aspects, viz., the age at death, the quality of the hair and the macrocephaly, of both patients are discussed.

Menkes disease is a rare inherited disorder of copper metabolism caused by mutations in the ATP7A gene. Its clinical course is characterized by early neurological regression, seizures, hypotonia and kinky friable hair. Neuroimaging typically reveals severe brain atrophy with subdural fluid collections and excessive tortuosity of cerebral arteries. The authors describe a case of Menkes disease with unusual imaging findings. The patient had macrocephaly and symmetrical bilateral confluent white matter changes with temporal cystic areas, reminiscent of megalencephalic leukodystrophy.

Menkes kinky hair syndrome, also known as trichopoliodystrophy, is a rare X-linked recessive, progressive neurodegenerative disorder characterized clinically by progressive psychomotor impairment, treatment-refractory seizures, and hair shaft abnormalities, most commonly pilli torti. The condition is related to a mutation in a copper transporting gene, located in the X-chromosome, resulting in deficiency of copper dependent enzymes. The diagnosis can be confirmed by a low plasma level of copper and ceruloplasmin. The prognosis of classical Menkes disease is poor. We report a case of Menkes kinky hair disease with characteristic clinical, laboratory, and radiological findings with significant macrocephaly (above 95th percentile for age). Reporting of this case is of significance because of its rarity and association with significant macrocephaly.

Clinical finding of cutis laxa, characterized by wrinkled, redundant, sagging, nonelastic skin, is of growing significance due to its occurrence in several different inborn errors of metabolism (IEM). Metabolic cutis laxa results from Menkes syndrome, caused by a defect in the ATPase copper transporting alpha (ATP7A) gene; congenital disorders of glycosylation due to mutations in subunit 7 of the component of oligomeric Golgi (COG7)-congenital disorders of glycosylation (CDG) complex; combined disorder of N- and O-linked glycosylation, due to mutations in ATPase H+ transporting V0 subunit a2 (ATP6VOA2) gene; pyrroline-5-carboxylate reductase 1 deficiency; pyrroline-5-carboxylate synthase deficiency; macrocephaly, alopecia, cutis laxa, and scoliosis (MACS) syndrome, due to Ras and Rab interactor 2 (RIN2) mutations; transaldolase deficiency caused by mutations in the transaldolase 1 (TALDO1) gene; Gerodermia osteodysplastica due to mutations in the golgin, RAB6-interacting (GORAB or SCYL1BP1) gene; and mitogen-activated pathway (MAP) kinase defects, caused by mutations in several genes [protein tyrosine phosphatase, non-receptor-type 11 (PTPN11), RAF, NF, HRas proto-oncogene, GTPase (HRAS), B-Raf proto-oncogene, serine/threonine kinase (BRAF), MEK1/2, KRAS proto-oncogene, GTPase (KRAS), SOS Ras/Rho guanine nucleotide exchange factor 2 (SOS2), leucine rich repeat scaffold protein (SHOC2), NRAS proto-oncogene, GTPase (NRAS), and Raf-1 proto-oncogene, serine/threonine kinase (RAF1)], which regulate the Ras-MAPK cascade. Here, we further expand the list of inborn errors of metabolism associated with cutis laxa by describing the clinical presentation of a 17-month-old girl with Leigh-like syndrome due to enoyl coenzyme A hydratase, short chain, 1, mitochondria (ECHS1) deficiency, a mitochondrial matrix enzyme that catalyzes the second step of the beta-oxidation spiral of fatty acids and plays an important role in amino acid catabolism, particularly valine.
