Noonan sendromu (NS) en sık görülen ve en bilinen RASopati olmakla birlikte, Noonan sendromu-multipl lentigines (NS-ML), kardiyofasiyokutanöz sendrom (KFKS), Costello sendromu (CS), nörofibromatozis tip 1 (NF1), Legius sendromu (LS) gibi sendromlar bu gruba dahil edilmektedir. Günümüzde RAS/MAPK yolağında RASopati veya Noonan spektrumu bozukluklara yol açan çok sayıda gen bildirilmiştir. Yeni nesil dizileme tekniklerindeki ilerlemeler ile de bu fenotipe yol açan pek çok yeni gen tanımlanmaktadır. Bu sendrom grubunu tanımlayan ortak bazı klinik özellikler olsa da genetik ve allelik heterojenite sınıflandırmayı zorlaştırmaktadır. Bu bölümde, RAS/MAPK yolağı ile RASopatilere yol açan farklı genlerin özellikleri ve bu hastalıklardaki genotip-fenotip ilişkisi anlatılmıştır.Publication Metadata only Change of menarcheal age in schoolgirls living in Istanbul over the last 12 years(2022-09-01) GÜRAN, TÜLAY; GÜRPINAR TOSUN, BUŞRA; HALİLOĞLU, BELMA; DEMİRCİOĞLU, SERAP; HIDIROĞLU, SEYHAN; BEREKET, ABDULLAH; GÜRAN T., Alir F., Arslan Y.

B., Yavas Abali Z., SEVEN MENEVŞE T., et al.Introduction: Thyrotropin-producing pituitary adenoma (TSHoma) is a very rare disease, representing less than 1% of the pituitary tumours, present with elevated thyroid hormones and normal/high TSH concentrations. Case Presentation: A 7-year-old boy with nervousness was referred by his psychiatrist for elevated free T4, T3 and TSH levels. Initial evaluation revealed an elevated -subunit.Pituitary MRI demonstrated a macroadenoma. The patient underwent a trans-sphenoidal tumour resection (TSS) which showed positive immunohistochemical staining for TSH, growth hormone, and prolactin in tumoral tissue. Euthyroidism was achieved for one year after TSS, then, recurrence of tumour with elevated TSH and thyroid hormone levels necessitated a re-operation with TSS followed by gamma-knife radiosurgery. The euthyroid state was achieved and lasted for 2.5 years this time, but, due to the recurrence, medical treatment had been commenced with cabergoline and octreotide. Euthyroidism was maintained for the last 4 years on monthly octreotide treatment. A repeat MRI demonstrated no pituitary mass but a mass in the sphenoidal sinus had been detected. Removal of this mass by surgery did not achieve euthyroidism. 68Ga-DOTA-TATE PET/CT showed residual tissue extending from the pituitary region to the sphenoid sinus.The patient\"s bone age was advanced 2 years at diagnosis which became 4 years in one year after the diagnosis and remained so throughout follow-up, leading to a final height of -3.3 SDS below his target height at the age of 16 years. Conclusion: The diagnosis, treatment, and follow-up of TSHomas are challenging and short stature due to accelerated bone maturation is a complication of paediatric TSHomas.Publication Metadata only Low-dose ACTH Stimulation Test: Comparison of Cortisol Response at 30, 40, and 60 Minutes(2022-09-01) GÜRAN, TÜLAY; GÜRPINAR TOSUN, BUŞRA; ARIKAN, HAZAL; DEMİRCİOĞLU, SERAP; BEREKET, ABDULLAH; GÜRPINAR TOSUN B., ARIKAN H., DEMİRCİOĞLU S., BEREKET A., GÜRAN T.Publication Metadata only A rare cause of monogenic obesity: Schaaf-Yang syndrome due to a novel MAGEL2 gene variant(2022-09-01) GÜRAN, TÜLAY; DEMİRCİOĞLU, SERAP; BEREKET, ABDULLAH; Abali Z.

B., ALAVANDA C., Helvacioglu D., Abali Z. Y., GÜRPINAR TOSUN B., ELTAN M., SEVEN MENEVŞE T., GÜRAN T., ARMAN A., et al.Objectives: Central precocious puberty (CPP) develops as a result of early stimulation of the hypothalamic-pituitary-gonadal (HPG) axis. The loss-of-function mutations in the Makorin-ring-finger3 (MKRN3) gene appear to be the most common molecular cause of familial CPP. We aimed to identify MKRN3 gene mutations in our CPP cohort and to investigate the frequency of MKRN3 mutations.Methods: 102 patients with CPP included. 53 of them had family history of CPP in the first and/or second-degree relatives. MKRN3 gene was analyzed by next-generation sequencing.Results: Possible pathogenic variants were found in 2/53 patients with family history of CPP (3.8%) and 1/49 patient without family history (2%). A novel heterozygous c.1A > G (p.Met1Val) mutation, a novel heterozygous c.683_684delCA (p.Ser228*) and a previously reported c.482dupC (Ala162Glyfs*) frameshift variations were detected. The two novel variants are predicted to be pathogenic in silico analyses.Conclusions: In our cohort, possible pathogenic variants in MKRN3 gene were detected in 2.9% of the total cohort, 3.8% of the familial and 2% of the nonfamilial cases, slightly lower than that reported in the literature. Two novel variants detected contribute to the molecular repertoire of MKRN3 defects in CPP. Classical pattern of paternal inheritance has been demonstrated in all three cases. However, the father of the patient 3 did not have history of CPP suggesting that the father inherited this variant from his mother and had phenotype skipping. Therefore, we emphasize that the absence of history of CPP in the father does not exclude the possibility of a MKRN3 mutation.
