We report an actionable secondary finding from whole-genome sequencing (WGS) of a 10-year-old boy with autism. WGS identified non-synonymous variants in several genes, including a nonsense mutation in the gene which is an X-linked cause of Kallmann syndrome. WGS can provide insights into complex genetic disorders such as autism, and actionable incidental findings can offer the potential for therapeutic interventions.

Background: Smell tests in children need to be standardized and validated, include odors familiar to children, and be defined by age-dependent standards. This study aimed to adapt the Sniffin Kids Test (SKT) for Polish children and conduct validation and evaluation of the Sniffin Kids Poland Test (SKPOL).
Methodology: The study included 382 children (4-14 years old) recruited in Poland, who were allocated into healthy (n=343) and sick (with subjective olfactory disorders, n=39), divided into 3 age subgroups, but also 13 anosmic children with Kallmann syndrome (KS) and olfactory bulb aplasia.

The Sprouty (Spry) proteins modulate signalling and regulate processes like cellular migration and proliferation. Here, we investigated a Spry4 alteration substituting a lysine at position 177 to an arginine, based on a mutation found in Kallmann syndrome, a genetically heterogeneous disease connected to reduced fibroblast growth factor receptor1 (FGFR) signalling. Using growth curves to evaluate proliferative and scratch assays to determine migrative capacities of the cells, in normal fibroblasts as well as in osteosarcoma-derived cells, we demonstrate that the modified Spry4 version hinders both processes, which the unaltered protein cannot do under the same conditions.

Background: Traditional treatments for congenital hypogonadotropic hypogonadism (CHH) primarily focus on human chorionic gonadotropin (hCG) monotherapy, combined gonadotrophin treatment or Testosterone replacement therapy, which has certain limitations in effectiveness. In recent years, pulsatile gonadotropin-releasing hormone (GnRH) pump treatment, capable of mimicking physiological hormone release patterns, has become a more preferred treatment option. However, there is still a scarcity of medium- and long-term studies in this regard.

Introduction: Olfaction is important for the quality of life; however, in Kallmann syndrome (KS), defective development results in olfactory dysfunction. Notably, the mechanism underlying olfactory development, especially in the olfactory epithelium (OE), which detects olfactory signals, remains unclear. Mutations in PROK2, which encodes prokineticin-2, have been identified in approximately 9% of the KS patients with olfactory defects.
