DHH gene

The DHH gene, also known as desert hedgehog, is a gene that plays a critical role in the development and function of certain cells and tissues in the body. It is one of several genes that are associated with various genetic disorders and syndromes. Mutations or changes in the DHH gene can lead to abnormalities and disorders related to the development and function of the peripheral nervous system and other organs.

Scientists have identified a number of different mutations in the DHH gene that are associated with various disorders and conditions. One such condition is Swyer syndrome, which is characterized by abnormal development of the gonads. Testing the DHH gene for these mutations can be done through genetic testing, such as karyotype testing. Additional genetic testing may be necessary to identify other genes that may also be involved in the development of these disorders.

Swyer syndrome

Swyer syndrome, also known as XY gonadal dysgenesis, is a rare genetic disorder listed in the National Institutes of Health Genetic and Rare Diseases Information Center (GARD) and the Online Mendelian Inheritance in Man (OMIM) catalog. It is primarily caused by changes in the DHH gene, which is a member of the Hedgehog signaling pathway.

Swyer syndrome is characterized by the development of female sexual characteristics in individuals with a 46,XY karyotype, typically associated with males. It is a pure gonadal dysgenesis disorder, meaning that affected individuals have abnormal development of the gonads but have normal peripheral secondary sexual characteristics.

Swyer syndrome is one of many disorders related to disorders of sex development (DSD) and is often identified during infancy or adolescence when individuals do not develop secondary sexual characteristics. Additional genetic testing may be necessary to confirm the diagnosis, such as karyotype analysis to determine the chromosomal abnormalities.

Scientific articles and genetic databases are valuable resources for information on Swyer syndrome and other related conditions. PubMed and OMIM are commonly used databases for genetic information, while GARD provides comprehensive information on genetic and rare diseases. Each database offers a variety of information, such as genetic variant databases, citation databases, and related articles.

In conclusion, Swyer syndrome is a rare genetic disorder caused by changes in the DHH gene. It is listed in various genetic and rare disease catalogs and can be identified through genetic testing and karyotype analysis. Further research and understanding of this disorder are necessary to provide appropriate care and support for affected individuals.

  • 46,XY sex reversal 1 – This disorder is characterized by individuals with male sex chromosomes (XY) developing female physical characteristics. These individuals have a normal male karyotype but develop a female phenotype due to abnormal development of the testes.
  • Partial alopecia with peritoneal sclerosis – This condition is characterized by partial hair loss and peritoneal sclerosis, which is the hardening or thickening of the peritoneum, the tissue lining the abdomen. The exact relationship between this condition and the DHH gene is not clearly understood.
  • Gonadal dysgenesis XY type associated with hedgehog-related protein mutations – This condition is associated with mutations in the DHH gene and affects the development of the gonads. Individuals with this disorder may have abnormal male or female genitalia or ambiguous genitalia.
  • Dominant external auditory canal atresia – This disorder is characterized by the absence or abnormal narrowing of the external auditory canal, which can lead to hearing loss. The DHH gene has been identified as one of the genetic causes for this condition.
