Novel PIK3R1 gene mutation associated with SHORT syndrome: a case report of a 15-year-old female
Abstract
Abstract Objectives To present the clinical journey and management of a 15-year-old female with SHORT syndrome, highlighting the diagnostic challenges and the novel genetic mutation identified. Case presentation A 15-year-old Filipino female was initially seen in a dermatology clinic at 9 years old for axillary skin darkening, indicative of acanthosis nigricans. Early evaluations revealed elevated blood glucose levels, resulting in a pediatric diabetes diagnosis without the usual hyperglycemic symptoms. Her medical history was notable for premature birth, intrauterine growth restriction, a cardiac murmur from patent ductus arteriosus and a bicuspid aortic valve, delayed teething, and distinct dysmorphic features. Genetic testing identified a novel PIK3R1 gene mutation. Treatment with metformin significantly improved her glycemic control and lipid profiles. The patient also displayed delayed puberty and polycystic ovary syndrome-like symptoms, but growth hormone deficiency was excluded. Endocrine evaluation for her short stature and lipodystrophy confirmed the presence of the PIK3R1 mutation. Conclusions This case highlights the importance of thorough endocrine and genetic evaluations in patients with complex clinical presentations like SHORT syndrome. The identification of a novel PIK3R1 gene mutation expands the understanding of the genetic basis of this syndrome and underscores the need for individualized treatment approaches.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
