A De Novo POLD1 Mutation Associated With Mandibular Hypoplasia, Deafness, Progeroid Features, and Lipodystrophy Syndrome in a Family With Werner Syndrome

Short stature as the first manifestation of mandibular hypoplasia, deafness, progeroid features and lipodystrophy (MDPL) syndrome

Mandibular hypoplasia, deafness, progeroid features and lipodystrophy (MDPL) syndrome is an autosomal dominant disorder caused by heterozygous mutations in the polymerase, delta 1, catalytic subunit (POLD1) gene. Here, we report the clinical description of a 10-year-old boy who first presented with short stature and hypogonadism. We screened this patient for mutations by focused exome sequencin...

A Frame-Shift Mutation in CAV1 Is Associated with a Severe Neonatal Progeroid and Lipodystrophy Syndrome

A 3-year-old female patient presenting with an unknown syndrome of a neonatal progeroid appearance, lipodystrophy, pulmonary hypertension, cutis marmorata, feeding disorder and failure to thrive was investigated by whole-genome sequencing. This revealed a de novo, heterozygous, frame-shift mutation in the Caveolin1 gene (CAV1) (p.Phe160X). Mutations in CAV1, encoding the main component of the c...

Mandibular Involvement in Recurrent Multifocal Osteomyelitis Associated with SAPHO Syndrome

Introduction: SAPHO syndrome is defined as the association of a group of rare sterile osteoarticular disorders and inflammatory skin diseases whose etiology, although not yet determined, probably involves genetic, immunological and infectious mechanisms. The recurrent multifocal osteomyelitis, an inflammatory disease, can be associated with this syndrome even as a single event.  Case Report:...

A Novel Splice Site Mutation in HPS1 Gene is Associated with Hermansky-Pudlak Syndrome-1 (HPS1) in an Iranian Family

Congenital Generalized Lipodystrophy in a Youth Presented with Sclerotic and Lytic Bone Lesions; a Family with AGPAT2 Mutation

BackgroundCongenital generalized lipodystrophy (CGL) is a rare disease. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time. Bone cyst i...
