Cathelicidin represents a new target for manipulation of skin inflammation in Netherton syndrome.
Biochim Biophys Acta Mol Basis Dis. 2020 10 01, 1866, (10):165831.
Netherton syndrome (NS) is a severe ichthyosis caused by inactivating mutations in the SPINK5 gene encoding the serine protease inhibitor LEKTI. Spink5 mice recapitulate NS and die perinatally from extensive dehydration as a result of a severe defect of the epidermal barrier. We showed that deletion of Klk5 in Spink5 rescues neonatal lethality (Furio et al., 2015). However, Spink5Klk5 mice developed skin shedding and inflammation during the first week from birth and the majority (70%) (...)Voir sur Pubmed

Neonatal epidermolysis bullosa: lessons to learn about genetic counseling.
J Dermatolog Treat. 2021 Feb , 32, (1):29-32.
Epidermolysis Bullosa (EB) is a heterogeneous group of congenital blistering diseases that usually presents in the neonatal period. EB is classified into three major categories, each with many subtypes based on the precise location at which separation or blistering occurs, namely epidermolysis bullosa simplex (EBS), junctional epidermolysis bullosa (JEB) and dystrophic epidermolysis bullosa (...)Voir sur Pubmed

XPC deficiency increases risk of hematologic malignancies through mutator phenotype and characteristic mutational signature.
Nat Commun. 2020 11 17, 11, (1):5834.
Recent studies demonstrated a dramatically increased risk of leukemia in patients with a rare genetic disorder, Xeroderma Pigmentosum group C (XP-C), characterized by constitutive deficiency of global genome nucleotide excision repair (GG-NER). The genetic mechanisms of non-skin cancers in XP-C patients remain unexplored. In this study, we analyze a unique collection of internal XP-C tumor genomes including 6 leukemias and 2 sarcomas. We observe a specific mutational pattern and an average (...)Voir sur Pubmed
The involvement of nucleotide excision repair proteins in the removal of oxidative DNA damage.
Nucleic Acids Res. 2020 11 18, 48, (20):11227-11243.
The six major mammalian DNA repair pathways were discovered as independent processes, each dedicated to remove specific types of lesions, but the past two decades have brought into focus the significant interplay between these pathways. In particular, several studies have demonstrated that certain proteins of the nucleotide excision repair (NER) and base excision repair (BER) pathways work in a cooperative manner in the removal of oxidative lesions. This review focuses on recent data (...)Voir sur Pubmed
AP1S1 missense mutations cause a congenital enteropathy via an epithelial barrier defect.
Hum Genet. 2020 Oct , 139, (10):1247-1259.
Congenital diarrheal disorders (CDD) comprise > 50 monogenic entities featuring chronic diarrhea of early-onset, including defects in nutrient and electrolyte absorption, enterocyte polarization, enteroendocrine cell differentiation, and epithelial integrity. Diarrhea is also a predominant symptom in many immunodeficiencies, congenital disorders of glycosylation, and in some defects of the vesicular sorting and transporting machinery. We set out to identify the etiology of an intractable (...)Voir sur Pubmed
Naxos disease - a narrative review.
Expert Rev Cardiovasc Ther. 2020 Nov , 18, (11):801-808.
Naxos disease is a rare entity that manifests with woolly hair, keratosis of extremities, and cardiac manifestations that resemble arrhythmogenic right ventricular cardiomyopathy. It is inherited in an autosomal recessive pattern and mutations affecting plakoglobin and desmoplakin have been identified. There is an increased risk of arrhythmias, including sudden cardiac death at a young age. Right ventricular systolic dysfunction often progresses and left ventricular involvement may also (...)Voir sur Pubmed

A novel RAB39B mutation and concurrent de novo NF1 mutation in a boy with neurofibromatosis type 1, intellectual disability, and autism: a case report.
BMC Neurol. 2020 Sep 01, 20, (1):327.
Mutations in RAB39B at Xq28 causes a rare form of X-linked intellectual disability (ID) and Parkinson's disease. Neurofibromatosis type 1 (NF1) is caused by heterozygous mutations in NF1 occurring de novo in about 50% of cases, usually due to paternal gonadal mutations. This case report describes clinical and genetic findings in a boy with the occurrence of two distinct causative mutations in NF1 and RAB39B explaining the observed (...)Voir sur Pubmed

RIN2 and BBS7 variants as cause of a coincidental syndrome.

BBS7 and RIN2 variants cause Bardet Biedl syndrome and RIN2 syndrome respectively. We investigated a consanguineous family in which five individuals manifested different phenotypes. Whole-exome sequencing analyses of the individual with multiple phenotypes revealed homozygosity for novel pathogenic variants in his DNA sample; a frameshift variant in RIN2 (c.1938delT) and a splice-site variant in BBS7 (c.1677-1G > A). Other affected individuals were homozygous for a variant in only one of (...)Voir sur Pubmed
Skin wrinkling of the upper arms: a case of mid-dermal elastolysis.
Dermatol Online J. 2020 Apr 15, 26, (4).
Mid-dermal elastolysis is a rare acquired elastic tissue disorder with about 100 cases reported in the literature. It is characterized by localized patches of finely wrinkled skin on the shoulder and upper extremities and a band-like loss of elastic tissue in the mid-dermal layer on biopsy. Some patients may have symptoms of discomfort, erythema, and/or pruritis. Mid-dermal elastolysis is predominantly seen in young to middle-aged Caucasian females and extensive skin involvement may lead to (...)Voir sur Pubmed

Recombination-induced revertant mosaicism in ichthyosis with confetti and loricrin keratoderma.
J Dermatol Sci. 2020 Feb , 97, (2):94-100.
Revertant mosaicism refers to a condition in which a pathogenic germline mutation is spontaneously corrected in somatic cells, resulting in the presence of two or more cell populations with different genotypes in an organism arising from a single fertilized egg. If the revertant cells are clonally expanded due to a survival advantage over the surrounding mutant cells, patients benefit from this self-healing phenomenon which leads to the development of milder-than-expected clinical (...)Voir sur Pubmed
