*a single-gene disorder is the result of a ‘single mutated gene’*
.
(over 4000 human diseases are caused by ‘single-gene defects’)
(‘single-gene disorders’ can be passed on to ‘subsequent generations’ in several ways)
(genomic imprinting and uniparental disomy, however, may affect inheritance patterns)
(the divisions between recessive and dominant types are not “hard and fast”, although the divisions between autosomal and X-linked types are (since the latter types are distinguished purely based on the chromosomal location of the gene))
(for example, achondroplasia is typically considered a dominant disorder, but children with two genes for achondroplasia have a severe skeletal disorder of which achondroplasics could be viewed as carriers)
(‘sickle-cell anemia’ is also considered a ‘recessive condition’, but heterozygous carriers have increased resistance to malaria in early childhood, which could be described as a ‘related dominant condition’)
(when a couple where 1 partner or both are ‘sufferers’ (or ‘carriers’) of a ‘single-gene disorder’ wish to have a child, they can do so through in vitro fertilization, which means they can then have a ‘pre-implantation genetic diagnosis’ to check whether the ’embryo’ has the ‘genetic disorder’)
