Objective: To describe a novel KAL1 mutation in patients affected by Kallmann syndrome.
Setting: Endocrinology Clinic of the João de Barros Barreto University Hospital - Federal University of Pará, Brazil.
Methods: Clinical examination, hormone assays and sequencing of exons 5, 6 and 9 of the KAL1 gene in four Brazilian brothers with Kallmann syndrome.
Results: Detected a novel KAL1 mutation, c.612G.A/p.Trp204*, in four hemizygous brothers with Kallmann syndrome, and five heterozygous female family members.
Conclusion: The novel p.Trp204* mutation of the KAL1 gene results in the production of a truncated anosmin-1 enzyme in patients with Kallmann syndrome. This finding broadens the spectrum of pathogenic mutations for this disease.

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.

Kallmann syndrome is a rare disorder characterized by hypogonadotropic hypogonadism and an impaired sense of smell (anosmia or hyposmia) caused by congenital defects in the development of the gonadotropin-releasing hormone (GnRH) and olfactory neurons. Mutations in several genes have been associated with Kallmann syndrome. However, genetic testing of this disorder often reveals variants of uncertain significance (VUS) that remain uninterpreted without experimental validation.

Article Synopsis
- * Genetic variations (polymorphisms) in the PKs and PKR genes have been associated with conditions like infertility, neuroendocrine disorders, Hirschsprung's syndrome, central precocious puberty, and Kallmann syndrome.
- * The study aims to highlight how these genetic variations impact disease development and outcomes, positioning the PK system as a potential target for therapy and a marker for diagnosis in related health issues.

Article Synopsis
- * It's inherited in various ways, primarily X-linked recessive and autosomal forms, leading to symptoms like infertility, impotence, and microgenitalia in affected individuals.
- * Early diagnosis and intervention, including genetic testing and medical therapy, are crucial for managing symptoms and promoting the development of secondary sexual characteristics.

The Fibroblast growth factor (FGFs) family consists of at least 22 members that exert their function by binding and activating fibroblast growth factor receptors (FGFRs). The Fgf8/FgfD subfamily member, Fgf17, is located on human chromosome 8p21.3 and mouse chromosome 14 D2.
