CAMFAK syndrome
Encyclopedia
CAMFAK syndrome is an acronym used to describe a rare inherited neurologic
disease, characterized by peripheral and central demyelination of nerves, similar to that seen in Cockayne syndrome
. The name "CAMFAK" comes from the first letters of the characteristic findings of the disease: cataract
s, microcephaly
, failure to thrive
, and kyphoscoliosis
. The disease may occur with or without failure to thrive and arthrogryposis
.
CAMFAK syndrome is inherited in an autosomal recessive manner. This means the defective gene responsible for the disorder is located on an autosome
, and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder. The parents of an individual with an autosomal recessive disorder both carry
one copy of the defective gene, but usually do not experience any signs or symptoms of the disorder.
Neurology
Neurology is a medical specialty dealing with disorders of the nervous system. Specifically, it deals with the diagnosis and treatment of all categories of disease involving the central, peripheral, and autonomic nervous systems, including their coverings, blood vessels, and all effector tissue,...

Kyphoscoliosis
Kyphoscoliosis describes an abnormal curvature of the spine in both a coronal and sagittal plane. It is a combination of kyphosis and scoliosis. Kyphoscoliosis is a musculoskeletal disorder causing chronic underventilation of the lungs and may be one of the major causes of pulmonary hypertension...

Characteristics
Low birth weight and a bird-like face may be the first signs. Severe intellectual deficit and death within the first decade are typical.Genetics
CAMFAK syndrome is inherited in an autosomal recessive manner. This means the defective gene responsible for the disorder is located on an autosome
Autosome
An autosome is a chromosome that is not a sex chromosome, or allosome; that is to say, there is an equal number of copies of the chromosome in males and females. For example, in humans, there are 22 pairs of autosomes. In addition to autosomes, there are sex chromosomes, to be specific: X and Y...

Genetic carrier
A genetic carrier , is a person or other organism that has inherited a genetic trait or mutation, but who does not display that trait or show symptoms of the disease. They are, however, able to pass the gene onto their offspring, who may then express the gene...
