    Western Sydney Genetics Program, The Children's Hospital at Westmead, Sydney, NSW, 2145, Australia.
    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.

    Aging changes to the lower eyelids and midface include pseudoherniated orbital fat, tear trough deformity, lid laxity, and dermatochalasis. Surgical repair often aims at treating redundant skin or orbital fat malposition with a lower eyelid blepharoplasty. Either a transcutaneous or transconjunctival approach may be used, though recent trends have favored the transconjunctival technique if procedures require more than simple skin excision. Read More

    Relapsing bullous amyloidosis of the oral mucosa and acquired cutis laxa in a patient with multiple myeloma: a rare triple association.

    Department of Dermatology, Hospital Universitario La Paz, Madrid, Spain.
    It is well known that primary systemic amyloidosis [light chain (AL) amyloidosis] is associated with hidden dyscrasia or multiple myeloma. Acquired cutis laxa (cutis laxa acquisita; CLA) has also been described in patients with plasma cell dyscrasias, including multiple myeloma. We report a case in which haemorrhagic oral bullae were the first sign of an undiagnosed primary systemic amyloidosis related to multiple myeloma IgG-λ and previously diagnosed CLA. Read More

    Autosomal dominant cutis laxa with progeroid features due to a novel, de novo mutation in ALDH18A1.
    J Hum Genet 2017 Jun 23;62(6):661-663. Epub 2017 Feb 23.
    Department of Genetics, Children's Hospital of Eastern Ontario, Ottawa, Ontario, Canada.
    De novo dominant mutations in the aldehyde dehydrogenase 18 family member A1 (ALDH18A1) gene have recently been shown to cause autosomal dominant cutis laxa with progeroid features (MIM 616603). To date, all de novo dominant mutations have been found in a single highly conserved amino acid residue at position p.Arg138. Read More

    Effect of R119G Mutation on Human P5CR1 Dynamic Property and Enzymatic Activity.

    Pyrroline-5-carboxylate reductase (P5CR1) is a universal housekeeping enzyme that catalyzes the reduction of Δ1-pyrroline-5-carboxylate (P5C) to proline with concomitant oxidation of NAD(P)H to NAD(P). The enzymatic cycle between P5C and proline is important for function in amino acid metabolism, apoptosis, and intracellular redox potential balance in mitochondria. Autosomal recessive cutis laxa (ARCL) results from a mutation in P5CR1 encoded by PYCR1. Read More

    The Histopathological Findings of Patients Who Underwent Blepharoplasty Due to Dermatochalasis.
    Semin Ophthalmol 2017 Feb 6:1-5. Epub 2017 Feb 6.
    a Department of Ophthalmology , Ankara Training and Research Hospital , Ankara , Turkey.
    Purpose: To assess changes in lymphatic vessels, collagen, and elastic fiber structure in excised tissues with dermatochalasis (DC).

    Methods: In this prospective histopathological study, 70 upper eyelid skins of 35 patients operated on for dermatochalasis were compared with 10 eyelid skins of 10 patients operated on for other diagnoses. In histopathological examination, the two groups of patients were compared with respect to number of lymphatic vessels, largest lymphatic vessel diameter, number of elastic fibers, number of macrophages, edema between collagen fibers, and depth of stromal collagen bed.

    Gamma-carboxylation, performed by gamma-glutamyl carboxylase (GGCX), is an enzymatic process essential for activating vitamin K-dependent proteins (VKDP) with important functions in various biological processes. Mutations in the encodinggene are associated with multiple phenotypes, amongst which vitamin K-dependent coagulation factor deficiency (VKCFD1) is best known. Other patients have skin, eye, heart or bone manifestations. Read More
