Caregiver burden in Bardet-Biedl syndrome: findings from the CARE-BBS study

The CARE-BBS study reports on the caregiver burden associated with hyperphagia and obesity among patients with BBS. A multi-country survey was used to quantify the caregiver burden, which was found to be multifaceted and complex.

Forsythe E, et al. Orphanet J Rare Dis. 2023;18(1):181.

MC4R Journal

Burden of hyperphagia and obesity in Bardet-Biedl syndrome: a multicountry survey

Research into the impact of hyperphagia on the lives of caregivers and patients with BBS has been limited, until now. The CARE-BBS study launched a multi-country survey to quantify the physical and emotional burden associated with hyperphagia in BBS, which was described amongst others as "broad" and "negative".

MC4R Journal

Clinical and molecular diagnosis of Bardet-Biedl syndrome

This article explores the extensive clinical heterogeneity and main features of BBS. It aims to define the role of the different BBS genes and discuss various strategies for the clinical and molecular diagnosis of BBS.

Solarat C, Valverde D. Methods in Cell Biology. 2023;176:125–137.

MC4R Journal

Genetic contributors to obesity

The current research landscape of obesity caused by genetic impairments is summarised in this article. There is a focus on the known prevalence and hidden burden of obesity caused by genetic impairments, genetic drivers of appetite regulation, the importance of genetic testing and clinical features of monogenic and syndromic obesity.
