A recently described genetic disorder has been associated with 13q12.3 microdeletion spanning three genes, namely, KATNAL1, LINC00426, and HMGB1. Here, we report a new case with similar clinical features that we have followed from birth to 5 years old. The child carried a complex rearrangement with a double translocation: 46,XX,t(7;13)(p15;q14),t(11;15)(q23;q22). Array-CGH identified a de novo microdeletion at 13q12.2q13.1 spanning 3-3.4 Mb and overlapping 13q12.3 critical region. Clinical features resembling those reported in the literature confirm the existence of a distinct 13q12.3 microdeletion syndrome and provide further evidence that is useful to characterize its phenotypic expression during the 5 years of development.

Introduction: Hypospermatogenesis is a common histopathological subtype of non-obstructive azoospermia and is characterized by a decrease in the total number of germ cells within the seminiferous tubule as a result of spermatogenic failure. Determination of genetic factors before intracytoplasmic sperm injection can prevent the inheritance of these factors, as hypospermatogenesis patients gives high successful sperm retrieval rate. This study aimed to identify the structural variants associated with idiopathic hypospermatogenesis (iHS) by analyzing patient cohorts diagnosed with azoospermia using whole exome sequencing.

Objective: Prenatal diagnosis of fetal 13q34 microdeletion is a rare condition, which may present with abnormal fetal development, including facial dysmorphism, mental retardation, and developmental delay. We present a pregnant woman in whom the fetus presented with a 0.24-cm ventricular septal defect at 20 weeks of gestation, with fetal 13q34 (113610612-115092648) deletion.

Objective: Prenatal detection of complex chromosomal rearrangements (CCR) is extremely rare, but is of great clinical importance, since CCR can be causative of different congenital disorders. We present an exceptionally rare case of prenatally diagnosed Saethre-Chotzen syndrome (SCS) rising as a consequence of chromothripsis involving chromosomes 5, 7 and 11 and deletion of TWIST1 gene.
Case Report: Brachycephaly, hypertelorism, flat face, micrognathia, relative macroglossia and small posterior fossa were noted on ultrasound examination at 28th gestational week.

Objective: To report a rare 17q12 microduplication family.
Case Report: A 29-year-old woman (gravida 1, para 0) underwent amniocentesis at 21 weeks' gestation because of double bubble sign and polyhydramnios of the fetus on prenatal ultrasound. Chromosomal microarray analysis (CMA) from this family revealed a 1.

Introduction: 22q11 deletion syndrome (22q11DS) results from a microdeletion on chromosome 22 and is the most common microdeletion disorder in humans, affecting 1 in 2148 live births. Clinical manifestations vary widely among individuals and across different life stages. Effective management requires the involvement of a specialized multidisciplinary team.
