A Rare Case of Skeletal Dysplasia: Homozygous Mutation in ACAN Gene

Arslan Gulcin , Hazan Filiz , Kirkgoz Tarik , Ozkan Behzat

Spondylo-epimetaphyseal dysplasia -ACAN (SEMD- ACAN) is a rare form of osteo-chondrodysplasia that represents a group of vertebral, epiphyseal, and metaphyseal dysplasia. This genetic condition is caused by biallelic loss-of-function mutations in the ACAN gene, which encodes for aggrecan, an essential component of the extracellular matrix in cartilage. Biallelic loss-of-function mutations in this gene result in a range of characteristic symptoms, including disproportionate sho...

Achieving optimal metabolic control can be extremely challenging in some children and adolescents with T1DM. The adherence to multiple injections/day is among the leading causes of suboptimal control. Recently insulin degludec/aspart co-formulation (70%IDeg+30%IAsp: IDegAsp) has become available. Because of the longer-duration of IDeg, and retained individual pharmacokinetics of IDeg and IAsp, we wanted to test insulin IDegAsp's efficacy in our patients with po...

Recurrent Hypoglycemia in a Preschooler Girl with Overgrowth: Isolated ACTH-Deficiency with a Novel TPIT Mutation

Abali Zehra Yavas , Yesil Gozde , Kirkgoz Tarik , Kaygusuz Sare Betul , Turan Serap , Bereket Abdullah , Guran Tulay

Objective: Congenital isolated ACTH deficiency (IAD) is a rare autosomal recessive disorder that is characterised by low levels of plasma ACTH and cortisol with normal pituitary structure and hormones. Clinical presentation can occur in the neonatal period, as well as later in childhood. Here, we report a patient with IAD due to a novel TPIT mutation.Case: A 48/12 years old girl presented with loss of concioussness and found to be hypoglycemic...

Delayed Diagnosis of a Patient with Antley-Bixler Syndrome

Kirkgoz Tarik , Bas Serpil , Yavas Abali Zehra , Turan Serap , Bereket Abdullah , Guran Tulay

Objective: Antley-Bixler syndrome Type 1 (ABS1) is a rare form of craniosynostosis characterized by multiple dysmorphic features, radio-humeral synostosis and urogenital abnormalities due to P450 oxidoreductase (POR) gene mutations. ABS is also associated with adrenal and gonadal failure which are sometimes underrecognized due to predominance of skeletal findings in various clinics. We report a female patient with very characteristic skeletal and facial features of AB...

An Unusual Cause of Short Stature

Betul Kaygusuz Sare , Atay Zeynep , Kirkgoz Tarik , Guran Tulay , Bereket Abdullah , Turan Serap

Objectives: Spondyloenchondrodysplasia with immune dysregulation (SPENCDI) is an immunoosseous dysplasia combining the typical metaphyseal and vertebral bone lesions with immune dysfunction and neurologic involvement which is caused by mutations in ACP5 gene encoding tartrate resistant acid phosphatase 5. Here, we report a three year old girl presented with primary hypothyroidism, developmental delay and thrombocytopenia and diagnosed as SPENCDI.<p class="abstext"...

Isolated Congenital Central Hypothyroidism due to a Novel Mutation in TSH Beta Subunit Gene

Kirkgoz Tarik , Ozhan Bayram , Cetin Ozan , Kaygusuz Sare Betul , Turan Serap , Bereket Abdullah , Guran Tulay

Objective: Congenital isolated thyrotropin (TSH) deficiency is a rare condition due to autosomal recessive defects in TSHβ, TBL1X, IGSF1, TRHR genes. There are a few patients described with TSHβ mutations to date. These patients display the typical manifestations of severe untreated congenital hypothyroidism. Most patients are unrecognized, even in newborns screening settings due to unelevated TSH levels, which results in severe growth fail...

Persistent Mullerian Duct Syndrome: Rare But Important Aetiology of an Inguinal Hernia and Cryptorchidism in Boys

Bereket Abdullah , Bugrul Fuat , Kirkgoz Tarik , Karadeniz Cerit Kivilcim , Canmemis Arzu , Turan Serap , Picard Jean-Yves , Tugtepe Halil , Guran Tulay

Background: Anti-Mullerian hormone (AMH), secreted by immature Sertoli cells, provokes the regression of male fetal Mullerian ducts. Loss of function mutations in genes coding AMH (AMH) or its receptor (AMHRII) lead to the persistent Mullerian duct syndrome (PMDS) which is characterized by the presence of uterus, fallopian tubes, cervix and vagina in otherwise normally virilized 46,XY males. Typical clinical features along with plasma AMH levels and genotypin...

Background: Liquid chromatography-mass spectrometry (LC-MS) based panels of steroid hormones and their precursors offer a distinct pattern of steroid metabolome for various disorders of adrenal and gonadal steroidogenesis. However, it may not be easy to handle this high throughput data rapidly in clinical setting which requires expert opinion for correct interpretations. Analytical results of steroid panelling can be allied to automated review systems to simpl...

Background: Hypersensitivity reactions to gonadotropin releasing hormone analogues (GnRHa) is a rare but serious side effect . Besides, local reactions, urticaria, anaphylaxis, serum disease, Henoch Schonlein Purpura (HSP) have been reported during GnRHa treatment.. Clinicians should be aware of the potential association of GnRHa with systemic hypersensitivity reactions.Case reports: Here, we report nine girls with syste...
