Familial paraganglioma syndrome type 1 (PGL-1) is maternally imprinted, caused by SDHD mutations on the paternally inherited allele, and presents with paragangliomas and pheochromocytomas that are usually benign. We describe a kindred with a germline c.57delG SDHD mutation that demonstrates an aggressive and possibly expanded phenotype. Eight individuals across four generations were heterozygous for the c.57delG SDHD mutation. The three with known paternal inheritance were clinically affected. The aggressive phenotype was manifested by a neck paraganglioma with distant metastases, and to a lesser degree a neck paraganglioma infiltrating into local connective tissue and a pheochromocytoma presenting at age 8 y. A pulmonary capillary hemangioma may expand the SDHD phenotype. We conclude that the c.57delG SDHD mutation may confer a more aggressive and possibly expanded phenotype than other SDHD mutations.

Abstract Objectives were to describe any bothersome symptom and severely bothersome symptoms in inpatient children with cancer and hematopoietic stem cell transplant (HSCT) recipients. We included children 8–18 years of age with cancer or HSCT recipients who were receiving active treatment for cancer, admitted to hospital, and expected to be in hospital 3 days later. We administered the self‐report Symptom Screening in Pediatrics Tool (SSPedi). We described those who identified any degree of symptom bother (at least “a little”) and those who rated the degree of bother as severe (“a lot” or “extremely”). Factors associated with severe symptoms and total SSPedi scores were examined using multiple logistic and linear regression. Among the 302 patients, 298 (98.7%) reported having any bothersome symptom and 181 (59.9%) had at least one severely bothersome symptom. In multiple regression, older children were significantly more likely to have at least one severely bothersome symptom (15–18 and 11–14 years vs. 8–10 years; P = 0.008) and to have higher total SSPedi scores (P = 0.0003). Those with relapsed disease were more likely to have at least one severely bothersome symptom (odds ratio 2.1, 95% confidence interval 1.1–4.3; P = 0.037) and HSCT recipients were more likely to have higher symptom scores (β = 3.48, standard error = 1.6; P = 0.030). Almost all children receiving cancer therapies experience bothersome symptoms and 60% have at least one severely bothersome symptom. Older children experienced more severely bothersome symptoms and higher symptom scores. Future studies should follow children longitudinally to better understand the symptom trajectory and should institute interventions to manage symptoms.
