Congenital aniridia manifests with total or partial absence of the iris. The association disease PAX6 gene has been proven. Changes in structure lead to intrauterine pathology, visual organ malformation, malformation master regulator proteins organogenesis affecting various cells’ differentiation (central nervous system cells included). Such disorders result into development PAX6-associated syn...

(Abstracted from J Pediatr 2022;244:148–153) Congenital heart defects are the most common cause of infant death linked to congenital malformations (CHDs). This group disorders therefore remains a for concern, despite improvements in medical and surgical management that have resulted higher survival rates.

Animal models provide a valuable tool for investigating the genetic basis and the pathophysiology of human diseases, and to evaluate therapeutic treatments. To study congenital retinal disorders, mouse mutants have become the most important model organism. Here we review some mouse models, which are related to hereditary disorders (mostly congenital) including retinitis pigmentosa, Leber's cong...

Since Watson & Crick's 1953 description of the structure of DNA, significant progress has been achieved in the control of congenital disorders, most of which has benefited industrialized countries. Little advantage accrued to developing nations, most of which in the same time frame achieved a significant epidemiological transition, resulting in congenital disorders attaining public health signi...

Thyroid diseases in children and adolescents include acquired or congenital conditions, including genetic disorders either isolated part of a syndrome. Briefly, we will review the physiology pathophysiology thyroid gland its disorders. The aim this chapter is to describe abnormalities gland.

Congenital disorders of glycosylation are a rare group of metabolic disorders that can result in multiorgan disease. This article describes a novel finding of macular hypoplasia in congenital disorders of glycosylation type Ia.

Several congenital disorders may cause neutropenia. The recent advances in the field of molecular biology have facilitated our knowledge concerning pathophysiological mechanisms leading to these disorders. The molecular basis of disorders with defective myelopoiesis (severe congenital neutropenia and cyclic neutropenia) and disorders due to defective RNA processing (Shwachman Diamond syndrome a...
