Inheritance Patterns
Inheritance odds for Alpers Syndrome:
Overall odds of inheritance:
Usually both parents who are symptom-free genetic carriers of Alpers Syndrome; see inheritance of autosomal recessive diseases.
Sibling of diseased child odds of inheriting disease:
25% usually for an autosomal recessive disease.
Inheritance from one diseased parent odds:
Usually 0% of disease, 100% of being a genetic carrier if one parent has an autosomal recessive disease (not just carrier).
Inheritance from two diseased parents odds:
100%. Rare case where both parents are not carriers but actually have the autosomal recessive disease.
Genetic Carriers
Genetic carriers of Alpers Syndrome:
Inheritance from one carrier parent odds:
0% approximately.
Inheritance from two carrier parents odds:
25% disease, 50% chance carrier, 25% neither for autosomal recessive diseases.
Inheritance Features
Inheritance features for Alpers Syndrome:
Inheritance pattern:
Inheritance patterns for autosomal recessive diseases tend to be "horizontal".

About inheritance and genetics:
Inheritance of Alpers Syndrome refers to whether the condition is inherited
from your parents or "runs" in families.
The level of inheritance of a condition depends
on how important genetics are to the disease.
Strongly genetic diseases are usually inherited,
partially genetic diseases are sometimes inherited,
and non-genetic diseases are not inherited.
