Out-of-frame translation rescues a loss-of-function variant in a novel TBCE phenotype.

Context: Pathogenic variants in the TBCE gene, encoding tubulin-specific chaperone E crucial for tubulin folding, are linked to three severe neurodevelopmental disorders: Hypoparathyroidism-retardation-dysmorphism (HRD) syndrome, Kenny-Caffey syndrome type 1, and progressive encephalopathy with amyotrophy and optic atrophy.

Objective: We identified patients with a novel, milder TBCE-associated phenotype and aimed to characterize it at the clinical and molecular levels.

Materials And Methods: We conducted splicing analysis using deep NGS sequencing of RT-PCR products and detected TBCE through Western blotting.

Combination approach for -related parathyroid carcinoma in an adolescent female patient: a case report and literature review.

Parathyroid carcinoma (PC) is extremely rare in children and adolescent. PC is more often sporadic, but also it could be associated with germline mutations. The clinical features of primary hyperparathyroidism (PHPT) are nonspecific in children and adolescent, which delays the diagnosis for years.

[Intestinal ganglioneuromatosis as an early extra-endocrine manifestation of type 2B multiple endocrine neoplasia].

Multiple endocrine neoplasia type 2B (MEN 2B) is a rare variant of hereditary tumor syndromes caused by germinal mutations in the proto-oncogene RET. One of the components of the syndrome is multiple neurinomas, the early detection of  which is not always given due attention. We present a description of the case of MEN 2B, manifested in the first months of life by intestinal ganglioneuromatosis.

[A promising approach for therapy control in congenital adrenal hyperplasia. Problems of Endocrinology].

Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders requiring lifelong glucocorticoid replacement (GC) therapy. Lack of GC therapy leads to precocious puberty in boys, heterosexual development in girls, accelerated bone maturation and short final height in both sexes. In adolescence, the lack of GC therapy is the cause of menstrual disorders in girls and the development of TART in boys, as a result reducing the reproductive potential in both sexes.
