Recently, the knowledge of the genetic basis of fertility disorders has expanded enormously, mainly thanks to the use of next-generation sequencing (NGS). However, the genetic cause of infertility, in the majority of patients, is still undefined. The aim was to identify novel and recurrent pathogenic/likely pathogenic variants in patients with isolated infertility or puberty delay using a targeted NGS technique.

The impact of gene loss on the diversification of taxa and the emergence of evolutionary innovations remains poorly understood. Here, our investigation on the evolution of the Fibroblast Growth Factors (FGFs) in appendicularian tunicates as a case study reveals a scenario of "less, but more" characterized by massive losses of all Fgf gene subfamilies, except for the Fgf9/16/20 and Fgf11/12/13/14, which in turn underwent two bursts of duplications. Through phylogenetic analysis, synteny conservation, and gene and protein structure, we reconstruct the history of appendicularian Fgf genes, highlighting their paracrine and intracellular functions.

Cardiac development is a complex developmental process. The early cardiac straight tube is composed of an external myocardial layer and an internal endocardial lining. Soon after rightward looping, the embryonic heart becomes externally covered by a new epithelial lining, the embryonic epicardium.

Background: Kallmann syndrome (KS) is a rare genetic disorder marked by hypogonadotropic hypogonadism and either anosmia or hyposmia. It exhibits genetic heterogeneity, with mutations identified in only 30 % of cases, involving various genes such as KAL1, FGFR1, FGF8, CHD7, and SOX10. Here, we present a case of gonadotropin deficiency associated with KS, observed in both a mother and her daughter, the latter conceived through assisted reproductive technology using the mother's ovum.

Rhabdomyosarcoma (RMS), a malignancy of impaired myogenic differentiation, is the most common soft tissue pediatric cancer. PAX3-FOXO1 oncofusions drive the majority of the clinically more aggressive fusion-positive rhabdomyosarcoma (FP-RMS). Recent studies have established an epigenetic basis for PAX3-FOXO1-driven oncogenic processes.
