Background: Differences of sex development (DSDs) (conditions with atypical development of chromosomal, gonadal or anatomic sex) are classified into three groups: sex chromosome DSD, 46,XYDSD and 46,XX DSD. Around 1 newborn in 5000 presents ambiguous genitalia with a major challenge for male or female assignment. The identification of a genetic cause can contribute to a correct diagnosis and to optimize both management and genetic counselling.<p class="abs...

Background: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Background: Disorders of sex development (DSD) is a group of uncommon birth defects. Androgen excess in genetic females and androgen deficiency in genetic males can result in DSD. A child with ambiguous genitalia could be a virilized female or an under-masculinized male. Presented here is the socio-demographic profile, age at diagnosis, clinic 351al profile and etiology of patients with 46,XY DSD who are on follow up at our hospital.Objective and hypothe...

Background: X-linked lissencephaly with ambiguous genitalia (XLAG) syndrome which is a clinical spectrum of ARX mutations is presented with severe growth deficiency, abnormal genitalia and resistant seizures in neonatal period. We present a XLAG case which was formed due to a new ARX mutation and has an appearance of a huge interhemispheric cyst different from classic neuroradiological imagings.Case: The case which was diagnosed with prenatal hydrocephal...

Background: Genetic females with congenital adrenal hyperplasia (CAH) from severe 21-hydroxylase deficiency may be declared at birth as cryptorchid boys. Neonatal salt wasting leads to early reassignment but in its absence, the condition may go unrecognized.Case presentation: A term newborn with non-palpable gonads but a penile urethra was declared as boy. At 4.8 years, the child presented with sexual precocity. Height was +2.3 S.D., penil...

Case study: Baby A, a boy was delivered at 33 weeks gestation (birth weight 1.545 kg, 9th centile) by emergency caesarean section following maternal preeclampsia. He did not require any resuscitation at birth. He is the second baby of non-consanguineous Asian parents with no family history to note. Both parents are healthy and there was no history of maternal medication use. Baby A experienced respiratory distress syndrome and suspected sepsis. He developed a heart murmur, con...

Background: Neonatal diabetes (ND) is a rare monogenic form of diabetes presenting within the first six months of life. The most frequent causes include mutations in KCNJ11, ABCC8 and insulin genes, but up to 40% of patients remain without a molecular genetic diagnosis.Case presentation: Case 1: a female newborn of non-consanguineous parents, born at 35 weeks, SGA. She presented with hyperglycemia at second day of life...

Background: Collodion babies (CBs) are an inherited group of diseases characterized clinically by diffuses severely dry and scaling skin. Patients are generally born prematurely and/or small for gestational age (SGA). Congenital hypothyroidism is seen together with various congenital anomalies, although the mechanism involved is still unclear.Objective and hypotheses: To identify endocrinological problems, and particularly those concerning growth, in 42 ...

Introduction: Craniopharyngiomas are slow growing epithelial tumors located in the sellar or suprasellar region of the brain. Adamantinomatous subtype affects mainly children and accounts for 5–10% of all intracranial paediatric tumors. Diagnosed antenatal and neonatal craniopharyngiomas are very seldom, about 40 such cases have been detected to date. They are characterised by large size, progressive hydrocephalus and a poor prognosis.Aim: The aim o...

Background: Noonan syndrome (NS) is an autosomal-dominant inherited condition defined clinically by a short stature, specific phenotype, congenital heart disease, bleeding and hematologic abnormalities (particularly leukaemia). There is also a genetic heterogeneity, with all mutations involved in the RAS/mitogen-activated protein (MAP) kinase pathway and with PTPN11 gene mutations counting for almost 50% of patients.Objective and hypotheses: To describe ...
