Abstract We report the case of an 11‐year‐old Syrian girl born to consanguineous parents, who presents an ataxic gait from early childhood. On clinical examination, she presented a severe static ‐ kinetic cerebellar syndrome, walking without support is possible for short distances only. Strikingly, three consecutive MRIs did not show any sign of cerebellar abnormalities, but a brain positron emission tomography (PET) using [18F]‐fluorodeoxyglucose (FDG) demonstrated a clear decrease in glucose metabolism...
Abstract Kabuki syndrome is characterized by a variable degree of intellectual disability, characteristic facial features, and complications in various organs. Many variants have been identified in two causative genes, that is, lysine methyltransferase 2D (KMT2D) and lysine demethylase 6A (KDM6A). In this study, we present the results of genetic screening of 100 patients with a suspected diagnosis of Kabuki syndrome in our center from July 2010 to June 2018. We identified 76 variants (43 novel)...
Abstract Individuals with comorbidities are at higher risk of coronavirus disease 2019 (COVID‐19) and worse outcome, but little information has been available about patients with genetic diseases and COVID‐19. This study aims at evaluating the presence and outcome of COVID‐19 in a cohort of Italian patients with tuberous sclerosis complex (TSC) and/or lymphangioleiomyomatosis (LAM), and at reviewing the possible effects of mTOR inhibitors on SARS‐CoV‐2 infection. We included 102 unselected individuals...
Abstract Glutaric acidemia type 2 (GA2), also called multiple acyl‐CoA dehydrogenase deficiency, is an autosomal recessive disorder of fatty acid, amino acid, and choline metabolism resulting in excretion of multiple organic acids and glycine conjugates as well as elevation of various plasma acylcarnitine species (C4–C18). It is caused by mutations in the ETFA, ETFB, or ETFDH genes which are involved in the transfer of electrons from 11 flavin‐containing dehydrogenases to Coenzyme Q10 (CoQ10) of...
Abstract Autosomal recessively inherited pathogenic variants in genes associated with the renin–angiotensin–aldosterone system (RAAS) result in early onset oligohydramnios and clinical features of the Potter sequence, typically in association with proximal renal tubules dysgenesis. We describe two siblings and a first cousin who had severe oligohydramnios in the second trimester, and presented at birth with loose skin, wide fontanelles and sutures, and pulmonary insufficiency. Two had refractory...
Abstract The ciliary chondrodysplasias represent a group of clinically and genetically heterogeneous disorders that affect skeleton development. Cilia are organelles that project from the surface of many cell types and play an important role during prenatal and postnatal human development. Cranioectodermal dysplasia (Sensenbrenner syndrome, CED) is a ciliopathy primarily characterized by craniofacial, skeletal, and ectodermal abnormalities. To date six genes have been associated with CED: IFT122,...
Abstract Trichothiodystrophy, non‐photosensitive type 4 (TTD4), is a rare genetic disorder with an autosomal recessive mode of inheritance. It is characterized by coarse and brittle hair, anomalies of the tissues derived from the neuro‐ectoderm (skin, hair, and nails) and intellectual disability. We herein report two male siblings aged 13 and 16 years with TTD4 and a known homozygous pathogenic variant, c.229del [p.(Arg77Glyfs*76)] in exon 1 of MPLKIP (NM_138701.3). We herein highlight the clinical...
Abstract Dowling–Degos disease (DDD) is a rare autosomal‐dominant genodermatosis and it has been associated with hidradenitis suppurativa (HS). Deregulation of NOTCH pathway has been linked to the development of HS in DDD context (DDD‐HS). However, molecular alterations in DDD‐HS, including altered gene expression of NOTCH and downstream effectors that are involved in the follicular differentiation and inflammatory response, are poorly defined. We report two cases of patients diagnosed with DDD‐HS,...
Abstract Homozygous recessive or compound heterozygous mutations in SLC13A5‐gene as a cause of Early Infantile Epileptic Encephalopathy subtype 25 (OMIM 615905) were published in 2014. Previous clinical reports describe young patients, aged <34 years. We describe 54‐ and 56‐year‐old siblings and show that the disorder linked to SLC13A5 is not just a pediatric problem but may affect the patient for decades resulting in profound intellectual disability, severe motor handicap, and abnormal electroencephalography...

Efforts in genome sequencing in the Aspergillus genus have led to the development of quality reference genomes for several important species including A. nidulans, A. fumigatus, and A. oryzae. However, less progress has been made for A. flavus. As part of the effort of the USDA-ARS Annual Aflatoxin Workshop Fungal Genome Project, the isolate NRRL3357 was sequenced and resulted in a scaffold-level genome released in 2005. Our goal has been biologically driven, focusing on two areas: isolate variation...
Genome-wide analysis of transcriptome data in Chlamydomonas reinhardtii shows periodic patterns in gene expression levels when cultures are grown under alternating light and dark cycles so that G1 of the cell cycle occurs in the light phase and S/M/G0 occurs during the dark phase. However, alternative splicing, a process that enables a greater protein diversity from a limited set of genes, remains largely unexplored by previous transcriptome based studies in C. reinhardtii. In this study, we used...
Globe artichoke (Cynara cardunculus var. scolymus; 2n=2x= 34) is cropped largely in the Mediterranean region, being Italy the leading world producer; however, over time, its cultivation has spread to the Americas and China. In 2016, we released the first (v1.0) globe artichoke genome sequence (http://www.artichokegenome.unito.it/). Its assembly was generated using ~133-fold Illumina sequencing data and covers 725 of the 1,084 Mb genome, of which 526 Mb (73%) were anchored to 17 chromosomal pseudomolecules....
