Adrenoleukodystrophy facts Also known as Addison-Schilder Disease, Siemerling-Cruetz Feldt Disease, ALD Also known as Addison-Schilder Disease, Siemerling-Cruetz Feldt Disease, ALD Rare disease Rare disease 1 in 20,000 people have disease1 in 20,000 people have disease Leads to brain damage, failure of adrenal glands, death Leads to brain damage, failure of adrenal glands, death Part of leukodystropies group Part of leukodystropies group
Symptoms Damages myelin- tissue that insulates nerves and help conduct impulses Damages myelin- tissue that insulates nerves and help conduct impulses Transporter protiens are missing in people with ALD Transporter protiens are missing in people with ALD Long Chain Fatty Acids build up in body Long Chain Fatty Acids build up in body Can damage adrenal glands and brain Can damage adrenal glands and brain
Inheritance X-linked disease X-linked disease Abnormal gene located on x- chromosomeAbnormal gene located on x- chromosome Inherited through autosomal recessive inheritance Inherited through autosomal recessive inheritance Gene carrying mutation is located on one of the 1-22 chromosome pairsGene carrying mutation is located on one of the 1-22 chromosome pairs
For example: If a female carrier has daughters with an unaffected man, the daughters have a 50% chance of becoming a carrier. If a female carrier has daughters with an unaffected man, the daughters have a 50% chance of becoming a carrier. If a female carrier has sons with an unaffected man, the sons have a 50% chance of developing the disease If a female carrier has sons with an unaffected man, the sons have a 50% chance of developing the disease
If both parents are carriers, there is a 50% chance that the children will be carriers, a 25% chance that they will be normal, and a 25% chance that they will have the disease. If both parents are carriers, there is a 50% chance that the children will be carriers, a 25% chance that they will be normal, and a 25% chance that they will have the disease.
Three Types of ALD Childhood cerebral form Childhood cerebral form Most common typeMost common type Adult-onset form Adult-onset form Mild forms of ALD found in carriers Mild forms of ALD found in carriers

Diagnosis Blood levels taken to see if there are elevated very-long chain fatty acids Blood levels taken to see if there are elevated very-long chain fatty acids Chromosome study are taken to see if there is an ABCD1 gene mutation Chromosome study are taken to see if there is an ABCD1 gene mutation MRI taken of brain to show damage to white matter of brain MRI taken of brain to show damage to white matter of brain
