Abstract
Bisalbuminemia is a rare, typically benign condition marked by the presence of a bifid albumin band on serum protein electrophoresis. It can either be inherited due to a point mutation or acquired in association with various medical conditions, most commonly diabetes mellitus. Bisalbuminuria, the presence of bifid albumin in urine, may or may not accompany bisalbuminemia. Both conditions are often discovered incidentally during screening for monoclonal gammopathy. Bisalbuminemia and related variants provide insights into albumin's genetic diversity and functional roles, influencing clinical diagnostics and research in human genetics. Understanding these variants aids in distinguishing benign conditions from potential disease states, guiding appropriate clinical management. In this case-based review, we present a case of hereditary bisalbuminemia identified unexpectedly during an investigation of a positive Direct Antiglobulin Test Coombs in an adult female patient. This review aims to highlight the key features of bisalbuminemia, a rare condition that should be recognized by clinicians.

A Multi-Gene Panel to Identify Lipedema-Predisposing Genetic Variants by a Next-Generation Sequencing Strategy. J Pers Med 2022; 12:268. [PMID: 35207755 PMCID: PMC8877075 DOI: 10.3390/jpm12020268] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 02/07/2022] [Accepted: 02/08/2022] [Indexed: 12/25/2022] Open
Abstract
Lipedema is a disabling disease characterized by symmetric enlargement of the lower and/or upper limbs due to deposits of subcutaneous fat, that is easily misdiagnosed. Lipedema can be primary or syndromic, and can be the main feature of phenotypically overlapping disorders. The aim of this study was to design a next-generation sequencing (NGS) panel to help in the diagnosis of lipedema by identifying genes specific for lipedema but also genes for overlapping diseases, and targets for tailored treatments. We developed an NGS gene panel consisting of 305 genes potentially associated with lipedema and putative overlapping diseases relevant to lipedema. The genomes of 162 Italian and American patients with lipedema were sequenced. Twenty-one deleterious variants, according to 3 out of 5 predictors, were detected in PLIN1, LIPE, ALDH18A1, PPARG, GHR, INSR, RYR1, NPC1, POMC, NR0B2, GCKR, PPARA in 17 patients. This extended NGS-based approach has identified a number of gene variants that may be important in the diagnosis of lipedema, that may affect the phenotypic presentation of lipedema or that may cause disorders that could be confused with lipedema. This tool may be important for the diagnosis and treatment of people with pathologic subcutaneous fat tissue accumulation.
