    The genetic and molecular basis of idiopathic hypogonadotropic hypogonadism. To date, at least 25 different genes have been implicated in causing gonadotropin-releasing hormone (GnRH) deficiency conditions such as Kallmann syndrome (KS) or other forms of congenital hypogonadotropic hypogonadism (CHH) through a disruption in the production or activity of GnRH.

    Another clinical sign of CHH, more specifically Kallmann syndrome, is a lack of a sense of smell due to the altered migration of GnRH neurons on the olfactory placode. Kallmann syndrome can also be shown through MRI imaging with irregular morphology or aplasia of the olfactory bulb and olfactory sulci.

  7. Anosmin-1 - Wikipedia

    en.wikipedia.org/wiki/Anosmin-1

    Absence or damage to the protein results in Kallmann syndrome in humans, which is characterized by loss of olfactory bulbs and GnRH secretion leading to anosmia and hypothalamic hypogonadotropic hypogonadism. Anosmin-1 is coded by the KAL-1 gene, which is found on the X chromosome. Anosmin-1 is 100 kilodaltons and is expressed on the outside of ...

    en.wikipedia.org/wiki/Congenital_Anosmia

    This condition can occur in isolation or as part of a syndrome, such as Kallmann syndrome or CHARGE syndrome. [11] There is no known cure for congenital anosmia. Management focuses on safety precautions to mitigate risks associated with the inability to smell, such as not detecting smoke or gas leaks. [10]

    Glanzmann's thrombasthenia is an abnormality of the platelets. [2] It is an extremely rare coagulopathy (bleeding disorder due to a blood abnormality), in which the platelets contain defective or low levels of glycoprotein IIb/IIIa (GpIIb/IIIa), which is a receptor for fibrinogen.
