PLoS Genetics, 6(2).1553-7404https://doi.org/10.1371/journal.pgen.1000833https://journals.plos.org/plosgenetics/article?id=10.1371/journal.pgen.1000833http://hdl.handle.net/11452/28527The histiocytoses are a heterogeneous group of disorders characterised by an excessive number of histiocytes. In most cases the pathophysiology is unclear and treatment is nonspecific. Faisalabad histiocytosis (FHC) (MIM 602782) has been classed as an autosomal recessively inherited form of histiocytosis with similarities to Rosai-Dorfman disease (RDD) (also known as sinus histiocytosis with massive lymphadenopathy (SHML)). To elucidate the molecular basis of FHC, we performed autozygosity mapping studies in a large consanguineous family and identified a novel locus at chromosome 10q22.1. Mutation analysis of candidate genes within the target interval identified biallelic germline mutations in SLC29A3 in the FHC kindred and in two families reported to have familial RDD. Analysis of SLC29A3 expression during mouse embryogenesis revealed widespread expression by e14.5 with prominent expression in the central nervous system, eye, inner ear, and epithelial tissues including the gastrointestinal tract. SLC29A3 encodes an intracellular equilibrative nucleoside transporter (hENT3) with affinity for adenosine. Recently germline mutations in SLC29A3 were also described in two rare autosomal recessive disorders with overlapping phenotypes: (a) H syndrome (MIM 612391) that is characterised by cutaneous hyperpigmentation and hypertrichosis, hepatomegaly, heart anomalies, hearing loss, and hypogonadism; and (b) PHID (pigmented hypertrichosis with insulin-dependent diabetes mellitus) syndrome. Our findings suggest that a variety of clinical diagnoses (H and PHID syndromes, FHC, and familial RDD) can be included in a new diagnostic category of SLC29A3 spectrum disorder.eninfo:eu-repo/semantics/openAccessAdenosineLymphadenopathyApoptosisGrowthCellsGeneGenetics & heredityAllelesAnimalsBase sequenceBreast neoplasmsCell line, tumorCell proliferationChromosomes, human, pair 10Colony-forming units assayDNA mutational analysisEmbryo, mammalianFamilyFemaleGene expression regulationGenetic lociHistiocytosis, sinusHumansMiceMolecular sequence dataMutationNucleoside transport proteinsPhysical chromosome mappingRNA, small interferingSyndromeUrinary bladder neoplasmsArticle0002752627000292-s2.0-776491965636220140240Genetics & hereditySinus Histiocytosis; Hypertrichosis; EmperipolesisAdenosineCarrier proteins and binding proteinsEquilibrative nucleoside transporterEquilibrative nucleoside transporter 3Protein slc29a3Small interfering RNAUnclassified drugENT3 proteinMouseNucleoside transporterSLC29A3 proteinHumanAnimal tissueArticleAutosomal recessive inheritanceBladder cancerBreast cancerCancer cell cultureCell proliferationCell strain HEK293Chromosome 10qClinical articleClinical featureConsanguinityControlled studyEmbryoEmbryo developmentFaisalabad histiocytosisGene expressionGene locusGene mappingGene mutationHeLa cellHistiocytosisHumanHuman cellMouseMutational analysisNonhumanNucleotide sequencePathogenesisPhenotypeProtein protein interactionRosai Dorfman diseaseAlleleAnimalAnimal embryoBladder tumorBreast tumorChromosome 10Chromosome mapClonogenic assayFamilyFemaleGene expression regulationGeneticsMetabolismMolecular geneticsMutationPathologySinus histiocytosisSyndromeTumor cell line
