Case history: We present the case of a 72-year-old female who was referred to the endocrinology service following the identification of a pathogenic germline mutation in the SDHA gene (c.91C>T, p.Arg32*) as part of a genetic panel for hypertrophic cardiomyopathy. There was no personal or family history of phaeochromocytoma or paraganglioma (PPGL), gastrointestinal stromal tumours or pituitary adenoma.Investigations: Our patient was reviewed ...

Background: Childhood growth monitoring aims to identify growth failure and detect underlying pathology. According to UK guidance, height <-2.7 standard deviation score (SDS) (<0.4th percentile) is used as the referral threshold. Additional referral criteria include height deficit (HSDS-target height SDS) <-2.0 and height velocity (HV) SDS <-1.3. Lack of routine HV and mid-parental height calculation, combined with stricter cut-offs compared to other European c...

Background: Phaeochromocytoma and paraganglioma (PPGL) are highly heritable, with 30-40% due to a germline pathogenic variant. An additional 40% of tumours will harbour a somatic variant. Understanding the variant status of a tumour enables molecular classification. Liquid biopsy offers a novel approach to non-invasive diagnostics by harnessing the ability to detect small amounts of circulating-free DNA (cfDNA) and performing genomic sequencing. There are few ...

Background: Pathogenic variants in genes encoding Succinate Dehydrogenase subunits B and D (SDHB/SDHD) predispose to Phaeochromocytoma and Paraganglioma (PPGL). Cascade genetic screening identifies relatives at risk and allows surveillance screening to enable early detection of PPGLs.Methods: Retrospective analysis of genetic databases and hospital records between January 2000 and December 2018 identified relatives carrying SDHB and <em...
