Inheritance syndrome is typically inherited in an autosomal dominant pattern, meaning that a mutation in one copy of the affected gene is enough to cause the syndrome. This means that an affected individual has a 50% chance of passing the syndrome on to their offspring. Rarely, inheritance syndrome can also be inherited in an autosomal recessive or X-linked pattern.
If the parents are unaffected and the child is affected, it may suggest an autosomal recessive inheritance pattern. This means that both parents are carriers of a recessive gene mutation, which is expressed in the affected child. Each parent has one normal and one mutated copy of the gene, leading to a 25% chance of the child inheriting both mutated copies.
Refsum's disease has a recessive pattern of inheritance and affects populations from Northern Europe, particularly Scandinavians most frequently.
The inheritance pattern of the BRCA1 gene is dominant.
Marfan syndrome is an autosomal dominant disorder. An affected person has a 50% chance of passing it on to each offspring, regardless of gender.
Gregor Johann Mendel is credited with discovering the pattern of genetic inheritance
By observing the proportion of affected offspring and whether males or females are more affected.
A heterozygous individual who has one allele for a disease but is not affected by it is considered a carrier. Carriers can pass the disease allele to their offspring but do not exhibit the symptoms themselves. This is common in genetic disorders that follow a recessive inheritance pattern.
