45,X/47,XYY mosaicism is quite rare, and, like 45,X/46,XY, it can be associated with mixed gonadal dysgenesis, Turner syndrome or apparently normal male/female phenotype. An infant aged 16 days, born full-term via spontaneous vaginal delivery to a 32 year-old G1P1 woman. His pregnancy and perinatal period were both uncomplicated except for maternal long QT syndrome. There was third degree cousin consanguinity between the parents. There was no any virilizing drug use and no mat...

Background: Mutations in CYP21A2 are the most common cause of congenital adrenal hyperplasia (CAH). Even though disease linked mutations are rarely classified as founder, in this study, we describe a novel founder mutation, c.2T>C (p.M1?), inactivating the translation initiation codon.Objective and Hypotheses: We aimed to investigate genotype–phenotype correlation and population based origin of this novel mutation in CAH patients with 2...

Introduction: The association of precocious puberty and/or polycystic ovaries, delayed bone age and hypothyroidism is known as the Van Wyk and Grumbach syndrome (VWGS). Clinically this syndrome is a diagnostic challenge because hypothyroidism usually leads to pubertal and growth delay, whereas in case of VWGS hypothyroidism it leads to growth delay and precocious puberty. We report a boy with long-standing, untreated hypothyroidism who presented with precocious puberty.<p ...

Introduction: Automated insulin delivery systems provide significant improvement in the time in range(TIR) centered diabetes care. This study analyzes the real-word performance of Minimed 780G™system-Advanced Hybrid Closed Loop(AHCL) in children from a single center.Methods: Of the 93 children started to use AHCL between January 2021 and April 2022, 64 whose data could be accessed were included. 3,6,9 and 12 month-...

Background and Objectives: Enlargement and cystic changes in ovaries of patients with longstanding overt hypothyroidism has been observed in numerous case reports. But there is limited data about the effect of subclinical hypothyroidism (SH) on ovarian volume and ovarian cyst formation. We evaluated the relationship between serum thyroid stimulating hormone (TSH) level and ovarian volume and sonographic appearance in prepubertal girls with SH.<p class="abs...

Introduction: Isolated hypoaldestronism is a rare endocrinopathy in a limited number of patients who secrete normal level of cortisol, due to mutation in CYP11B2. In some cases clinical diagnosis can be late and genetic analysis showed difficulties.Case 1: A 7 month-old girl infant was referred to endocrinology department due to womiting, failure to thrive and severe hyponatremia with unexplained neutropenia. She was bor...

Introduction: With the development and use of automated insulin delivery (AID) technologies like Advanced Hybrid Closed Loop (AHCL or Minimed 780G) system, it becomes possible to achieve tighter glycemic control. A new parameter called “Time in Tight Range” (TITR, 70-140 mg/dL) has been proposed to evaluate glycemic control in the latest consensus on the use of continuous glucose monitoring (CGM) data in diabetes research. This study aims to assess...

Introduction: Aggrecan, a chondroitin sulfate proteoglycan encoded by the ACAN gene, is an important structural component of the cartilage matrix. Variants in the ACAN gene are associated with a group of skeletal dysplasias called aggrecanopathy, which shows a broad phenotypic spectrum. It has been reported that some heterozygous variants in this gene are responsible for the etiology of familial or idiopathic short stature located at the lightest end of the sp...

Entrance: HOXA gene deletions cause an appearance characterized by short stature, mild developmental delay, characteristic face, small hands and feet, short and large thumbs, and urogenital malformations. Clinical signs may vary according to the content of the deletion region.Case: The case applied to our clinic with the complaint of short stature. It was learned that the patient was born at term 2500 gr and had bilatera...

Background: Approximately 10-15% of small for gestational age (SGA) newborns are at risk of having subnormal growth and persistent short stature. It is postulated that a large amount of persistent short stature results from genetic abnormalities, which are commonly characterized by dysmorphic features and developmental disorders.Aim: To uncover the genetic etiology of syndromic short stature children born SGA.<p clas...
