Anosmia, Isolated Congenital (ANIC)

What is Anosmia, Isolated Congenital (ANIC)?

Patients had reported anosmia, isolated congenital, often associated with other features, but in all cases, these other features were independent traits. Autosomal dominant inheritance is present in most cases, along with male-to-male transmission. All patients had only congenital anosmia.

Syndrome Synonyms

Anosmia – Familial Anosmia, Congenital

What gene change causes this syndrome?

Haplotype analysis showed that all affected individuals shared a common haplotype in the 18p11.23-q12.2 region, but up to date (2024), no gene has been established.

What are the main symptoms of Anosmia, Isolated Congenital?

  • Complete Loss of Smell Since Birth: Individuals are unable to detect any odors due to the congenital absence or dysfunction of the olfactory nerve or related structures.
  • Isolated Condition: Anosmia occurs without associated syndromic features or additional physical abnormalities, distinguishing it as an isolated condition.
  • Autosomal Dominant Inheritance: It is often inherited in an autosomal dominant manner, and cases with male-to-male transmission have been reported.

Possible clinical traits/features
Autosomal dominant inheritance, Anosmia

How is it diagnosed?

To find out if someone has a diagnosis of [Anosmia, Isolated Congenital, it is important to have a consultation and evaluation with a clinical genetic specialist.  Specialists may also suggest specific genetic testing or other types of tests to help reach a diagnosis.  FDNA’s AI technology can help speed up the diagnostic process by analyzing facial features and other health information.

Weiss-Kruszka syndrome (WSKA)

It is a multiple congenital anomaly syndrome that has been recently identified. There are just 24 potential cases currently reported worldwide. It is also known as Weiss-Kruska syndrome. The gene responsible for the disorder is the ZNF462 gene.

Yunis-Varon syndrome (YVS)

It is a rare genetic disease that affects multiple systems of the body. Its main symptoms affect the skeletal and nervous systems, as well as ectodermal tissue (hair and teeth). Since 1980 just 25 cases from 19 families have been diagnosed and recorded. This syndrome is also known as: Cleidocranial Dysplasia With Micrognathia, Absent Thumbs, And Distal Aphalangia

Xia-Gibbs syndrome (XIGIS)

It is a rare genetic syndrome associated mainly with intellectual disability. This syndrome is also known as: Mental Retardation, Autosomal Dominant 25; Mrd25 Changes in the AHDC1 gene are responsible for causing the syndrome. It is inherited in an autosomal dominant pattern, although all cases of the syndrome recorded so far have been the result of de novo or new mutations in the gene. In the case of autosomal dominant inheritance just one parent is the carrier of the gene mutation, and they have a 50% chance of passing it onto each of their children. Syndromes inherited in an autosomal dominant inheritance are caused by just one copy of the gene mutation. In some cases, a genetic syndrome may be the result of a de-novo mutation and the first case in a family. In this case, this is a new gene mutation which occurs during the reproductive process.
