It may be used to discover where the genes in question are located (x, y, or autosome chromosome), and to determine whether a trait is dominant or recessive. When a pedigree shows a condition appearing in a 50:50 ratio between men and women it is considered autosomal. When the condition predominantly affects males in the pedigree it is ...
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
Pedigrees are used to help detect many different genetic diseases. A pedigree can also be used to help determine the chances for a parent to produce an offspring with a specific trait. Four different traits can be identified by pedigree chart analysis: autosomal dominant, autosomal recessive, x-linked, or y-linked.
Autosomal dominant Charcot–Marie–Tooth disease type 2 with giant axons; Autosomal dominant GTP cyclohydrolase I deficiency; Autosomal dominant intellectual disability-craniofacial anomalies-cardiac defects syndrome; Autosomal dominant nocturnal frontal lobe epilepsy; Autosomal dominant partial epilepsy with auditory features; Autosomal ...
Autosomal dominant and autosomal recessive inheritance, the two most common Mendelian inheritance patterns. An autosome is any chromosome other than a sex chromosome.. In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
[24] [25] Some autosomal recessive disorders are common because, in the past, carrying one of the faulty genes led to a slight protection against an infectious disease or toxin such as tuberculosis or malaria. [26] Such disorders include cystic fibrosis, [27] sickle cell disease, [28] phenylketonuria [29] and thalassaemia. [30]
Autosomal dominant cerebellar ataxia, deafness, and narcolepsy; Autosomal dominant partial epilepsy with auditory features; Autosomal dominant porencephaly type I; Autosomal recessive axonal neuropathy with neuromyotonia; Autosomal recessive bestrophinopathy
