Genetic analysis can promote gene-adjusted, specific follow-up, and surveillance protocols for both patients and their families at risk. We report the case of a 7-yr-old boy with bilateral pheochromocytoma, which recurred a year after partial adrenalectomy. The patient's father developed bilateral pheochromocytomas at 25 yr of age. Both individuals possessed a novel heterogeneous in-frame duplication germline variant of VHL, yet neither exhibited other clinical manifestations of von Hippel-Lindau disease (VHL). Traditionally, VHL missense mutations have been associated with a higher risk of PPGL development, whereas truncating mutations typically confer a lower risk. In-frame duplication variants are rarely observed in patients with VHL but may lead to changes in the three-dimensional structure of the translated protein, similar to truncating variants. Our analysis suggests that these in-frame duplications of amino acids in specific regions may cause pheochromocytomas in a manner similar to missense variants. Further accumulation of VHL cases with various genotypes and standardized open-access worldwide databases, including longitudinal and specific clinical data linked to genotypes, is required. It is crucial to consider genetic analyses for pediatricians who may diagnose childhood-onset PPGL.","PeriodicalId":10678,"journal":{"name":"Clinical Pediatric Endocrinology","volume":"33 4","pages":"229-237"},"PeriodicalIF":1.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442702/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In all participants, BMI-SDS significantly correlated with WBC and platelet counts. Platelet count correlated with serum leptin and glucose levels, whereas WBC count correlated with serum leptin, insulin, HOMA-IR, and glucose levels.

At 11 yr and 7 mo of age, the patient experienced severe thirst and hyperglycemia (331-398 mg/dL). Laboratory tests revealed elevated levels of glycated hemoglobin (HbA1c) (47 mmol/mL, 6.5%) and the Homeostatic Model for Insulin Resistance (HOMA-IR) (3.4). Blood glucose self-monitoring demonstrated grossly normal blood glucose levels, together with occasional postprandial hyperglycemia, and a few episodes of hypoglycemia. An oral glucose tolerance test revealed mild hyperglycemia and a delayed peak insulin level. His laboratory indices improved over two years with self-control of diet and exercise. These results indicate that the initial presentation of RFX6-variant-associated diabetes includes occasional hyperglycemia and hypoglycemia in response to changes in lifestyle.

PS is distinguished based on perchlorate discharge test abnormality, goiter, and hypothyroidism in some patients. The pathophysiology of thyroid dysfunction in PS differs from that of autoimmune thyroid disease, in that it is considered to be caused by an iodide organification defect. It is believed that both diseases may incidentally coexist, and that SLC26A4 may play an important role in the etiology of autoimmune thyroid disease. Herein, we describe a case of a girl with hearing loss who had two pathogenic SLC26A4 variants and tested positive for thyroid peroxidase (TPO) antibody. She was diagnosed with hearing loss and vestibular aqueduct enlargement at the age of 4 yr. Deafness gene screening revealed two pathogenic SLC26A4 variants. As SLC26A4 variants can cause PS, the patient underwent thorough thyroid examination. Her thyroid gland was within the physiological range of mild enlargement. Although thyroid function test results were normal, the patient tested positive for TPO antibody. The patient was diagnosed with \"suspected PS\" and \"suspected Hashimoto's thyroiditis,\" both of which increase the risk of developing hypothyroidism. Evaluating the comorbidity of Hashimoto's thyroiditis with the SLC26A4 variant in terms of complications is critical.","PeriodicalId":10678,"journal":{"name":"Clinical Pediatric Endocrinology","volume":"33 4","pages":"219-223"},"PeriodicalIF":1.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11442696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, a genetic analysis (next-generation sequencing) was performed. In addition to the missense variant p.[Arg1940Cys] in CHD7, a novel nonsense variant, p. [Tyr110*] in SOX2 was identified. Although most features, including genital abnormalities and hearing loss, were clinically compatible with CHARGE syndrome caused by a CHD7 variant, optic nerve hypoplasia may have been caused by a pathogenic SOX2 variant. Prior research has shown that SOX2 is related to the development of male genitalia and the inner ear. Therefore, the genital abnormalities and hearing loss in this patient may be attributed to both the CHD7 and SOX2 variants.

Case 2 was mildly positive for GADA at the onset of diabetes, but became a high titer during the course of the disease. Fourteen months after the diagnosis of diabetes, he became mildly insulin deficient, and insulin therapy was initiated. However, his insulin secretory capacity was preserved for 60 mo after the onset.
