They include Gray Hair Syndromes (GHSs), a rare group of autosomal recessive genodermatosis hallmarked by inborn silvery gray hair. GHSs encompass Griscelli, Chediak\u2013Higashi, Elejalde, and Cross syndromes, which are all characterized by a broad spectrum of severe multisystem disorders, including neurological, ocular, skeletal, and immune system impairment. In this manuscript, we describe in detail the clinical, trichoscopic, and genetic features of a rare case of Griscelli syndrome; moreover, we provide an overview of all the GHSs known to date. Our report highlights how an accurate clinical examination with noninvasive methods, like trichoscopy, may play a crucial rule in diagnosis of rare and potentially lethal genetic syndromes such as Griscelli syndrome, in which timely diagnosis and therapy may modify the clinical course, quality of life, and likelihood of survival.<\/jats:p>","DOI":"10.3390\/medicina55030078","type":"journal-article","created":{"date-parts":[[2019,3,27]],"date-time":"2019-03-27T05:03:12Z","timestamp":1553662992000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Congenital Hypopigmentary Disorders with Multiorgan Impairment: A Case Report and an Overview on Gray Hair Syndromes"],"prefix":"10.3390","volume":"55","author":[{"given":"Laura Cristina","family":"Gironi","sequence":"first","affiliation":[{"name":"Department of Health Sciences, Amedeo Avogadro University of Eastern Piedmont, 28100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francesca","family":"Zottarelli","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Amedeo Avogadro University of Eastern Piedmont, 28100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gianfranco","family":"Savoldi","sequence":"additional","affiliation":[{"name":"Department of Pathology, Cytogenetic and Medical Genetics Unit, ASST Spedali Civili, 25123 Brescia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lucia Dora","family":"Notarangelo","sequence":"additional","affiliation":[{"name":"Pediatric Hematology and Oncology Unit, ASST Spedali Civili, 25123 Brescia, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Eleonora","family":"Basso","sequence":"additional","affiliation":[{"name":"Pediatric Onco-Haematology Division, City of Health and Science of Turin, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivana","family":"Ferrero","sequence":"additional","affiliation":[{"name":"Pediatric Onco-Haematology Division, City of Health and Science of Turin, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabio","family":"Timeus","sequence":"additional","affiliation":[{"name":"Pediatric Onco-Haematology Division, City of Health and Science of Turin, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franca","family":"Fagioli","sequence":"additional","affiliation":[{"name":"Pediatric Onco-Haematology Division, City of Health and Science of Turin, 10126 Turin, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luigi","family":"Maiuri","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Amedeo Avogadro University of Eastern Piedmont, 28100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Enrico","family":"Colombo","sequence":"additional","affiliation":[{"name":"Department of Translational Medicine, Amedeo Avogadro University of Eastern Piedmont, 28100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1636-8411","authenticated-orcid":false,"given":"Paola","family":"Savoia","sequence":"additional","affiliation":[{"name":"Department of Health Sciences, Amedeo Avogadro University of Eastern Piedmont, 28100 Novara, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6","DOI":"10.2340\/00015555-0794","article-title":"A practical classification of childhood hypopigmentation disorders","volume":"90","author":"Tey","year":"2010","journal-title":"Acta Derm.
