Melanocytes and Their Diseases
Downloaded from http://perspectivesinmedicine.cshlp.org/ on October 2, 2021 - Published by Cold Spring Harbor Laboratory Press Melanocytes and Their Diseases Yuji Yamaguchi1 and Vincent J. Hearing2 1Medical, AbbVie GK, Mita, Tokyo 108-6302, Japan 2Laboratory of Cell Biology, National Cancer Institute, National Institutes of Health, Bethesda, Maryland 20892 Correspondence: [email protected] Human melanocytes are distributed not only in the epidermis and in hair follicles but also in mucosa, cochlea (ear), iris (eye), and mesencephalon (brain) among other tissues. Melano- cytes, which are derived from the neural crest, are unique in that they produce eu-/pheo- melanin pigments in unique membrane-bound organelles termed melanosomes, which can be divided into four stages depending on their degree of maturation. Pigmentation production is determined by three distinct elements: enzymes involved in melanin synthesis, proteins required for melanosome structure, and proteins required for their trafficking and distribution. Many genes are involved in regulating pigmentation at various levels, and mutations in many of them cause pigmentary disorders, which can be classified into three types: hyperpigmen- tation (including melasma), hypopigmentation (including oculocutaneous albinism [OCA]), and mixed hyper-/hypopigmentation (including dyschromatosis symmetrica hereditaria). We briefly review vitiligo as a representative of an acquired hypopigmentation disorder. igments that determine human skin colors somes can be divided into four stages depend- Pinclude melanin, hemoglobin (red), hemo- ing on their degree of maturation. Early mela- siderin (brown), carotene (yellow), and bilin nosomes, especially stage I melanosomes, are (yellow).

Genetic Testing for Non-Cancerous Inheritable Diseases
Genetic Testing for Non-Cancerous Inheritable Diseases Policy Number: Original Effective Date: MM.02.009 03/01/2010 Line(s) of Business: Current Effective Date: HMO; PPO; QUEST Integration 12/30/2016 Section: Medicine Place(s) of Service: Outpatient I. Description A genetic test is the analysis of human DNA, RNA, chromosomes, proteins, or certain metabolites in order to detect alterations related to an inheritable disorder. This can be accomplished by directly examining the DNA or RNA that makes up a gene (direct testing), looking at markers co-inherited with a disease-causing gene (linkage testing), assaying certain metabolites (biochemical testing), or examining the chromosomes (cytogenetic testing). Genetic tests are conducted for a number of purposes, including predicting disease risk, newborn screening, determining clinical management, identifying carriers, and establishing prenatal or clinical diagnoses or prognoses in individuals, families, or populations. Expanded Carrier Screening The American College of Medical Genetics (ACMG ) defines expanded panels as those that use next- generation sequencing to screen for mutations in many genes, as opposed to gene-by-gene screening (e.g., ethnic-specific screening or panethnic testing for cystic fibrosis). An ACMG position statement states that although commercial laboratories offer expanded carrier screening panels, there has been no professional guidance as to which disease genes and mutations to include. This policy does not address oncology-related genetic testing or pre-implantation genetic diagnosis (PGD). II. Criteria/Guidelines Note: For familial assessments, unless otherwise specified, family will be considered: first-, second- and third- degree relatives on the same side of the family. The maternal and paternal sides should be considered independently. -

Phacomatosis Spilorosea Versus Phacomatosis Melanorosea
Acta Dermatovenerologica 2021;30:27-30 Acta Dermatovenerol APA Alpina, Pannonica et Adriatica doi: 10.15570/actaapa.2021.6 Phacomatosis spilorosea versus phacomatosis melanorosea: a critical reappraisal of the worldwide literature with updated classification of phacomatosis pigmentovascularis Daniele Torchia1 ✉ 1Department of Dermatology, James Paget University Hospital, Gorleston-on-Sea, United Kingdom. Abstract Introduction: Phacomatosis pigmentovascularis is a term encompassing a group of disorders characterized by the coexistence of a segmental pigmented nevus of melanocytic origin and segmental capillary nevus. Over the past decades, confusion over the names and definitions of phacomatosis spilorosea, phacomatosis melanorosea, and their defining nevi, as well as of unclassifi- able phacomatosis pigmentovascularis cases, has led to several misplaced diagnoses in published cases. Methods: A systematic and critical review of the worldwide literature on phacomatosis spilorosea and phacomatosis melanorosea was carried out. Results: This study yielded 18 definite instances of phacomatosis spilorosea and 14 of phacomatosis melanorosea, with one and six previously unrecognized cases, respectively. Conclusions: Phacomatosis spilorosea predominantly involves the musculoskeletal system and can be complicated by neuro- logical manifestations. Phacomatosis melanorosea is sometimes associated with ancillary cutaneous lesions, displays a relevant association with vascular malformations of the brain, and in general appears to be a less severe syndrome. -

Preconception Carrier Screening
Focusing on Personalised Medicine PRECONCEPTION CARRIER SCREENING Preconception carrier screening is an important tool for prospective parents to help them determine their risk of having a child affected with a heritable disease. In many cases, parents aren’t aware they are carriers and have no family history due to the rarity of some diseases in the general population. What is covered by the screening? Our Inherited Disease Panel tests over 300 genes associated with more than 700 unique commonly inherited diseases, including common forms of inherited deafness, blindness, heart disease, Parkinson’s disease, immunodeficiency, and various ataxias, anaemias, and treatable metabolic syndromes. The assay has been developed in conjunction with clinical molecular geneticists, and includeds genes listed in the NIH Genetic Test Registry. For a full list of genes and disorders covered, please see the reverse of this brochure. Why have Preconception Carrier Screening? Carrier screening prior to pregnancy enables couples to learn about their reproductive risk and consider a complete range of reproductive options, including whether or not to become pregnant, whether to use advanced reproductive technologies, such as preimplantation genetic diagnosis, or use donor gametes. Screening also allows couples to consider prenatal diagnosis and pregnancy management options in the event of an affected fetus. Whilst individually each disease tested is rare, around 25% of people will carry at least one abnormal mutation. These disorders are usually autosomal recessive, which means that a child must inherit a defective gene from each parent to have the disease. For autosomal recessive conditions, if a person is a carrier of the disease, they have one defective copy of the gene and one normal copy and typically don’t have any symptoms of the disease. -
