WebOne common way is by the condition's pattern of inheritance: autosomal dominant (DFNA), autosomal recessive (DFNB), X-linked (DFNX), or mitochondrial (which does not have a special designation). Each of these types of hearing loss includes multiple subtypes. DFNA, DFNB, and DFNX subtypes are numbered in the order in which they were first described. WebJul 8, 2009 · Several basic modes of inheritance exist for single-gene disorders: autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. However, not all genetic conditions will follow these patterns, and other rare forms of inheritance such as mitochondrial inheritance exist. (See table at the end of this section.)

WebX-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes; males have one X and one Y.

WebX-linked recessive inheritance refers to genetic conditions associated with variants in genes on the X chromosome. 3 Example: A male carrying such a variant will be affected, because he carries only one X chromosome. A female carrying a variant in one gene, with a normal gene on the other X chromosome, is generally unaffected. 3 WebAutosomal definition, occurring on or transmitted by a chromosome other than one of the sex chromosomes:Marfan syndrome is a connective tissue disorder inherited as an …
