geny opakující se

A set of genes descended by duplication and variation from some ancestral gene. Such genes may be clustered together on the same chromosome or dispersed on different chromosomes. Examples of multigene families include those that encode the hemoglobins, immunoglobulins, histocompatibility antigens, actins, tubulins, keratins, collagens, heat shock proteins, salivary glue proteins, chorion proteins, cuticle proteins, yolk proteins, and phaseolins, as well as histones, ribosomal RNA, and transfer RNA genes. The latter three are examples of reiterated genes, where hundreds of identical genes are present in a tandem array. (King & Stanfield, A Dictionary of Genetics, 4th ed)

geny supresorové

Genes that have a suppressor allele or suppressor mutation (SUPPRESSION, GENETIC) which cancels the effect of a previous mutation, enabling the wild-type phenotype to be maintained or partially restored. For example, amber suppressors cancel the effect of an AMBER NONSENSE MUTATION.

genetické poradenství

An educational process that provides information and advice to individuals or families about a genetic condition that may affect them. The purpose is to help individuals make informed decisions about marriage, reproduction, and other health management issues based on information about the genetic disease, the available diagnostic tests, and management programs. Psychosocial support is usually offered.

CSP

A communication process between a specially trained health professional and a person concerned about the genetic risk of disease. The person`s family and personal medical history may be discussed, and counseling may lead to genetic testing.
NCI

If you are expecting a baby or planning to have a baby, your doctor can run many tests to help assess the health of both you and your baby. Your doctor may also refer you for genetic counseling. Genetic counseling provides information and support to people who have, or may be at risk for, genetic disorders. A genetics professional meets with you to discuss genetic risks. You may follow up with genetic testing.

There are many reasons to seek genetic counseling. You may consider it if you

  • Have or are concerned you have an inherited disorder
  • Are pregnant or planning to be pregnant after age 35
  • Already have a child with a genetic disorder or birth defect
  • Have had two or more pregnancy losses or a baby who died
  • Have had ultrasound or screening tests that suggest a possible problem


MEDLINEPLUS

The process whereby an expert in hereditary disorders provides information about risk and clinical burden of a disorder or disorders to patients or relatives in families with genetic disorders as an aid to making informed and responsible decisions about marriage, children, early diagnosis, and handling disability.
