Summary We report a case of an 11-year-old girl presenting with a new diagnosis of diabetes associated with a heterozygous missense mutation in the insulin receptor (INSR) gene. This case highlights that INSR gene variants can be a cause for monogenic diabetes in children and adolescents and the need for genetic evaluation in atypical presentations of diabetes. We also describe the possible role of metformin in treating individuals with type A insulin resistance syndrome due to INSR gene variants. Learning points Insulin receptor (INSR) gene variants can be a cause of monogenic diabetes in children and adolescents. Genetic evaluation should be considered in children and adolescents with type 2 diabetes (T2D), particularly where there is an atypical presentation and/or positive family history. Metformin may have a role in the treatment of type A insulin resistance syndrome due to heterozygous mutation of the INSR gene.

Syndrome Donahue (leprechaunism) is a rare form of neonatal diabetes mellitus associated with INSR gene mutations. There are three types of insulin resistance syndrome: Donohue syndrome, Rabson—Mendenhall syndrome and insulin resistance type A. These syndromes are distinguished from one another by severity of symptoms, age of onset and age of death. Donohue and Rabson—Mendenhall syndromes are associated with biallelic mutations in the α-subunit or/and β-subunit of INSR gene and are characterized by more severe phenotype and poor prognosis. Patients with Donohue syndrome usually die within the first two years of life. Life expectancy of patients with Rabson—Mendenhall syndrome is 5—15 years. Most patients with insulin resistance type A have heterozygous mutations in the β-subunit and demonstrate mild phenotype. Here, we describe the first genetically confirmed case of syndrome Donahue in the Russian Federation.

Abstract Introduction The MEN 1 syndrome is an enigmatic disorder, manifesting a wide spectrum of disorders, in members of a family, harbouring the same gene mutation. We present one such family, with a MENIN gene mutation with marked diversity in the clinical presentation Clinical cases 1992: RB (Age: 13) presented with accelerated puberty, galactorrhoea and a lactotroph adenoma. Treated with Bromocriptine, followed by hypophysectomy and radiotherapy. He was on hormone replacement for hypopituitarism. 1996: He gained 21 kg of weight and had recurrent episodes of convulsions with unconsciousness.He had hypoglycaemia (13mg/dl; N >70), with hyperinsulinemia (58uIU/ml; N<25). MRI abdomen showed a mass (3.4 x 3.0 cm) over the tail of the pancreas for which a distal pancreatectomy was done (HPE: Neuroendocrine tumour). 2013: He had pain in the lower limbs with hypercalcemia (11.4mg%; N: 8.5-10.5) and hyperparathyroidism (329 pg/ml; N: 10-61) (MIBG Scan: parathyroid adenomas treated by bilateral inferior parathyroidectomy). 2016: He had hypoglycaemia with hyperinsulinemia with multifocal pancreatic NETs. These were enucleated at surgery. 2017: He developed Zollinger Ellison syndrome with raised basal gastrin levels (Gastrin: >200ng/ml; N<180) and multiple duodenal ulcers (Treatment: Pantoprazole). He simultaneously had recurrent hyperparathyroidism and underwent a total parathyroidectomy with allograft. The allograft initially showed evidence of hyperparathyroidism followed by hypoparathyroidism. His father VB (Age: 56) was seen by us in 1996 for skin lesions and a malignant thymic carcinoid, to which he succumbed to, shortly after the surgery. His aunt, SB (Age: 18), has a lactotroph adenoma with severe insulin resistance characterised by obesity, acanthosis nigricans and hyperandrogenism. 2009: His paternal uncle PB (Age: 54) had a pituitary macroadenoma. He underwent a hypophysectomy and was lost to follow up. 2018: PB had massive haemoptysis. A bronchoscopy showed nodules in the right lung which on biopsy revealed a NET. The whole body scan showed a hilar and mediastinal mass along with metastatic disease to the adrenals, liver, spine, skull and rectum. The histopathology examination revealed a malignant carcinoid Clinical lesson Whole exome sequencing of the two of the affected members showed mutations of the MENIN gene at exon 2 c.G2492T:p.G831V; g. chr10. This common mutation in the family was associated with a wide spectrum of diverse clinical manifestations which include the classic disease, malignant carcinoids of the lung and acromegaloid variant of Type A insulin resistance with hyperandrogenism. These observations suggest the unity amidst diversity in the enigmatic syndrome that encompasses MEN1.
