Aortic aneurysms requiring surgery in early childhood are rare. Herein we describe the case of a three-year-old with massive aneurysmal aortic dilation secondary to the rare and often lethal genetic disorder, cutis laxa. Initial thoracic aortic aneurysm gene panel was negative. Parents of the child were not known to be consanguineous, but high-density SNP array revealed several regions of homozygosity. This prompted targeted sequence analysis that identified a novel homozygous missense mutation in the gene for cutis laxa, EFEMP2...

In recent years the number of disorders known to affect amino acid synthesis has grown rapidly. Nor is it just the number of disorders that has increased: the associated clinical phenotypes have also expanded spectacularly, primarily due to the advances of next generation sequencing diagnostics. In contrast to the "classical" inborn errors of metabolism in catabolic pathways, in which elevated levels of metabolites are easily detected in body fluids, synthesis defects present with low values of metabolites or, confusingly, even completely normal levels of amino acids...

Homozygous or compound heterozygous mutations in fibulin-4 (FBLN4) lead to autosomal recessive cutis laxa type 1B (ARCL1B), a multisystem disorder characterized by significant cardiovascular abnormalities, including abnormal elastin assembly, arterial tortuosity, and aortic aneurysms. We sought to determine the consequences of a human disease-causing mutation in FBLN4 (E57K) on the cardiovascular system and vascular elastic fibers in a mouse model of ARCL1B. Fbln4(E57K/E57K) mice were hypertensive and developed arterial elongation, tortuosity, and ascending aortic aneurysms...

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...

Autosomal dominant cutis laxa (ADCL, OMIM #123700) is a rare connective tissue disorder characterized by loose, redundant skin folds that may be apparent form birth or appear later in life. Most severely affected areas are the neck, axillar regions, trunk, and groin. Typically, patients present with characteristic facial features including a premature aged appearance, long philtrum, a high forehead, large ears, and a beaked nose. Cardiovascular and pulmonary complications include bicuspid aortic valves, aortic root dilatation, and emphysema...

Cutis laxa is a heterogeneous condition characterized by redundant, sagging, inelastic, and wrinkled skin. The inherited forms of this disease are rare and can have autosomal dominant, autosomal recessive, or X-linked inheritance. Three of the autosomal recessive cutis laxa syndromes, namely cutis laxa IIA (ARCL2A), cutis laxa IIB (ARCL2B), and geroderma osteodysplastica (GO), have very similar clinical features, complicating accurate diagnosis. Individuals with these conditions often present with cutis laxa, progeroid features, and hyperextensible joints...

Pyrroline-5-carboxylate reductase (PYCR) is the final enzyme in proline biosynthesis, catalyzing the NAD(P)H-dependent reduction of Δ(1)-pyrroline-5-carboxylate (P5C) to proline. Mutations in the PYCR1 gene alter mitochondrial function and cause the connective tissue disorder cutis laxa. Furthermore, PYCR1 is overexpressed in multiple cancers, and the PYCR1 knock-out suppresses tumorigenic growth, suggesting that PYCR1 is a potential cancer target. However, inhibitor development has been stymied by limited mechanistic details for the enzyme, particularly in light of a previous crystallographic study that placed the cofactor-binding site in the C-terminal domain rather than the anticipated Rossmann fold of the N-terminal domain...

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. There is only one report in literature of this rare triple association; however, in that case the patient did not have oral mucosal involvement or bullous amyloidosis...

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. We report an 8-year-old male with a clinical diagnosis of autosomal dominant cutis laxa (ADCL) with progeroid features and a novel de novo missense mutation in ALDH18A1 (NM_002860.3: c.377G>A (p...

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. Specifically, the R119G mutation is reported to be linked to ARCL although it has not yet been characterized...

Pyrroline-5-carboxylate reductase (P5CR), an enzyme with conserved housekeeping roles, is involved in the etiology of cutis laxa. While previous work has shown that the R119G point mutation in the P5CR protein is involved, the structural mechanism behind the pathology remains to be elucidated. In order to probe the role of the R119G mutation in cutis laxa, we performed molecular dynamics (MD) simulations, essential dynamics (ED) analysis, and Molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) binding free energy calculations on wild type (WT) and mutant P5CR-NAD complex...

Defects of the V-type proton (H(+)) ATPase (V-ATPase) impair acidification and intracellular trafficking of membrane-enclosed compartments, including secretory granules, endosomes, and lysosomes. Whole-exome sequencing in five families affected by mild to severe cutis laxa, dysmorphic facial features, and cardiopulmonary involvement identified biallelic missense mutations in ATP6V1E1 and ATP6V1A, which encode the E1 and A subunits, respectively, of the V1 domain of the heteromultimeric V-ATPase complex. Structural modeling indicated that all substitutions affect critical residues and inter- or intrasubunit interactions...

We report the first Italian family affected by hereditary gelsolin amyloidosis (HGA), a rare autosomal dominant disease characterized by adult-onset slowly progressive cranial neuropathy, lattice corneal dystrophy, and cutis laxa. The index case was a 39-year-old male with a 9-year history of progressive bilateral facial nerve palsy. His mother had two episodes of acute facial palsy, and his maternal aunt and grandfather were also affected. Electrophysiological studies confirmed bilateral facial nerve involvement, without signs of peripheral polyneuropathy, and ophthalmological examination showed bilateral lattice corneal dystrophy, in both the index case and his mother...

BACKGROUND: Patients with hereditary gelsolin (AGel) amyloidosis (HGA) present with hanging skin (cutis laxa) and bilateral cranial neuropathy, and require symptomatic plastic surgery. Our clinical observation of tissue fragility prompted us to design a prospective study. METHODS: Twenty-nine patients with HGA undergoing surgery were interviewed and clinically examined. The height and thickness of skin folds in standard anatomical localizations were measured. The presence and distribution of amyloid in skin samples were analyzed using Congo red staining and immunohistochemistry using antibodies against gelsolin amyloid (AGel) subunit...

Most human neurodegenerative diseases are sporadic and appear later in life. Aging and neurodegeneration are closely associated, and recent investigations reveal that endoplasmic reticulum (ER) stress is involved in the progression of these features. Immunoglobulin heavy chain-binding protein (BiP) is an ER chaperone that is central to ER functions. We produced knock-in mice expressing a mutant BiP that lacked the retrieval sequence to elucidate the effect of a functional defect in an ER chaperone in multicellular organisms...

Pyrroline-5-carboxylate reductase (P5CR) encoded by PYCR1 gene is a housekeeping enzyme that catalyzes the reduction of P5C to proline using NAD(P)H as the cofactor. In this study, we used in silico approaches to examine the role of nonsynonymous single-nucleotide polymorphisms in the PYCR1 gene and their putative functions in the pathogenesis of Cutis Laxa. Among the 348 identified SNPs, 15 were predicted to be potentially damaging by both SIFT and PolyPhen tools; of them two SNP-derived mutations, R119G and G206W, have been previously reported to correlate with Cutis Laxa...

Gerodermia osteodysplastica is a recessive segmental progeroid disorder mainly characterized by wrinkled skin, generalized connective tissue weakness, infantile onset osteoporosis and normal intelligence. Coding mutations in GORAB, localized on chromosome 1q24.2, are the cause of this disease. 1q24 deletions underlie a spectrum of disorders with intellectual disability and ear abnormalities as phenotypic hallmarks. Here we report on an individual from Azerbaijan originating from a non-consanguineous couple showing short stature, cutis laxa, frequent fractures, facial dysmorphism, cup-shaped ears and intellectual disability...
