Two pedigrees with congenital bilateral anorchia in one sibling and testicular torsion at adolescence in another: a shared genetic predisposition?

Brachet Cécile , Chiniara Lyne , Vliet Guy Van

Background: In bilateral anorchia or vanishing testes syndrome, testicular function is normal during the embryonic period, as shown by the absence of Müllerian remnants and of hypospadias. Although normally differentiated, the penis may be small due to decreased testosterone secretion during the fetal period. In a normally virilised boy with non-palpable testes, with or without micropenis, the diagnosis is established by undetectable plasma anti-Müllerian hormone (AM...

Extreme Short Stature and Poor Pubertal Growth: When FBN1 is the Culprit

Brachet Cécile , Boros Emese , Soblet Julie , Vilain Catheline , Heinrichs Claudine

Introduction: Very short stature is a common presenting complain that gives rise to numerous investigations. FBN1 heterozygous mutations cause acromelic dysplasia syndromes. The phenotypic spectrum of these growth disorders is broad, ranging from short stature with short extremities, stiff joints, skin thickening with tracheal stenosis and cardiac valvulopathy to nearly isolated short stature. Here, we report on a girl with disproportionate short stat...

Heterozygous OTX2 Deletion in a Boy with Normal Eye Development and Normal Pituitary Function

Boros Emese , Boitsios Gramatina , Vilain Catheline , Balikova Irina , Heinrichs Claudine , Brachet Cécile

Introduction: Orthodenticle homeobox 2 (OTX2) is a transcription factor that plays a critical role in brain and eye development. Heterozygous deleterious mutations in this gene lead to eye malformation such as anophthalmia, microphthalmia, coloboma or optic nerve hypoplasia, normal or hypoplastic pituitary gland and normal or ectopic posterior pituitary gland with isolated growth hormone deficiency or combined pituitary hormone deficiency. There is no...
