Sjogren-Larsson syndrome : causes, symptoms, diagnosis, treatment

Sjogren-Larsson syndrome (SLS) is a hereditary ailment described by scaling skin (ichthyosis), scholarly incapacity, discourse irregularities, and spasticity. Influenced newborn children foster different levels of blushed skin with fine scales not long after birth.


SLS was first described in 1957 by Swedish doctors Sjogren and Larsson.

They reported a group of 28 associate patients from Vaster Otten Country, Sweden, who developed symptoms of what is now known as medical treatment or symptoms of Sjogren-Larsson syndrome: mental retardation, muscle spasm (spastic paraplegia), and itching.

At birth (congenital ichthyosis). SLS is a type of white matter dystrophy, which is a rare and advanced degenerative cellular disease that affects the brain, nerves, and nerve endings.

Low levels of this enzyme lead to skin and skin damage and other manifestations of Sjogren-Larsson syndrome.

If a person has a common genetic predisposition and a genetic predisposition to a disease, then he is responsible for the disease, but often he has no symptoms.

The impact on transgenic parents will be 25% in all their children and all pregnancies.

The risk of having a father is 50% in all pregnancies. Of all parents, a child has a 25% chance of having normal sex. The risk is the same for both men and women.

Parents of blood relatives (their families) are more likely to come in contact with children who have the same genetic makeup, which increases the chances of having children with gonorrhea.

Rate of occurrence

  • Other names for this situation:
  • ichthyosis congenital spastic syndrome and mental retardation
  • Incomplete FALDH
  • Lack of fat aldehyde dehydrates
  • Disease of oligohydramnios
  • Sjogren-Larsson syndrome.
  • SLS

Causes of Sjogren-Larsson syndrome

The quality that is changed in patients with Sjogren-Larsson condition is the aldehyde dehydrogenase 3A2 (ALDH3A2) quality.

Genes give guidelines to making proteins that assume a basic part in numerous elements of the body.

When a transformation of a quality happens, the protein item might be broken, wasteful, or missing. Contingent on the elements of the specific protein, this can influence numerous organ frameworks of the body, including the mind.

Changes (transformations) in the ALDH3A2 quality outcome in a lower-than-ordinary measure of a protein (greasy aldehyde dehydrogenase).

A lower measure of this compound prompts the layered and irritated skin and different highlights seen in Sjogren-Larsson disorder.

SLS is an autosomal passive condition. Most hereditary illnesses are dictated by the situation with the two duplicates of a quality, one got from the dad and one from the mother.

Recessive hereditary problems happen when an individual acquires two duplicates of an unusual quality for a similar characteristic, one from each parent.

If an individual acquires one ordinary quality and one quality for the illness, the individual will be a transporter for the infection yet typically won’t show manifestations.

The hazard for two transporter guardians to both pass the adjusted quality and have an influenced kid is 25% with every pregnancy.

Signs and Symptoms of Sjogren-Larsson syndrome

  • Premature birth is usually the first sign of Sjogren-Larsson syndrome.
  • The occurrence at birth, ichthyosis associated with SLS usually begins with a thick yellow-brown skin (hyperkeratosis).
  • This thick skin eventually grows into a perfect pillow, especially on the neck, lower abdomen, underarms, buttocks, and back of the knees (curves). Pruritus is unique to SLS.
  • The second stage of SLS is muscle spasm (spastic paresis).
  • It often affects the feet rather than the hands.
  • Another important clinical component of SLS is mental retardation. Most patients reach an average developmental life of 5-6 years.
  • Other symptoms that may be noticed include stiffness, difficulty speaking, short stature, spinal deformities (scoliosis), microcephaly and the brain (microcephaly).
  • The average life expectancy of male and female participants was 15 years, respectively 26 years.

Related problems:

Presence or absence of intense red skin (erythema).

Mail method.

The nature of the accompanying signals.

  • Refsum disease is a disease that affects genes called white matter dystrophy, in which the brain’s immune system (myelin sheath) is unable to grow due to fat loss problems. In the recessive genetic system.
  • The cause of this disorder is the accumulation of certain fatty acids (phytic acid) in the blood plasma and tissues. This is due to a genetic defect that causes this enzyme to degrade (metabolize) the acid. The required enzyme is missing.


SLS can be analyzed by a biochemical blood test that decides whether FADH movement is typical.

In expansion, since transformations in FADH are known to cause SLS, the quality can be sequenced to decide whether any changes are available.

This likewise gives the choice of hereditary and pre-birth testing, which can permit guardians to settle on educated choices about having youngsters.

The Genetic Testing Registry (GTR) gives data about the hereditary tests for this condition. The target group for the GTR is medical services suppliers and analysts.

Patients and shoppers with explicit inquiries regarding a hereditary test should contact medical services supplier or hereditary qualities proficient.

Treatment of Sjogren-Larsson syndrome

Sjogren-Larsson syndrome is incurable.

Treatment aims to eliminate their symptoms and may require a variety of different approaches to correct them.

Full-time pediatric and SLS staff may incorporate experts who assist with issues of the mind and focal sensory system (nervous system specialists), dermatologists who analyze and treat skin issues (dermatologists), experts who assess and ophthalmologists and ophthalmologists who have practical experience in the finding and treatment of illnesses of the skeleton and musculature Skeletal (orthotics) and actual advisors.

Low-fat weight control plans, like oils, fish, nuts, avocados, and meat, just as fatty oils, for example, milk and coconut oil, have been appeared to improve skin wellbeing in certain individuals wiped out.

Other techniques to diminish chipping incorporate the utilization of keratolytic or urea-containing creams or creams.

While there is no solution for muscle cramps, practice treatment can assist with works out. Different types of helpful help may incorporate strengthening and backing.

Individuals with SLS can profit by specific preparing to comprehend their psychological handicaps.

 Speech and language treatment has shown a few advantages in improving language capacity and improved relational abilities.


  • Evidence of Sjogren-Larsson disorder can be supposed at time of birth.
  • Medical diseases may be treated at the stage of 3 years when the obvious symptoms of the disease are usually clear. The victim often has no family history of the disease.
