What causes Nijmegen breakage syndrome?

What causes Nijmegen breakage syndrome?

Mutations in the NBN gene cause Nijmegen breakage syndrome. The NBN gene provides instructions for making a protein called nibrin. This protein is involved in several critical cellular functions, including the repair of damaged DNA. DNA can be damaged by agents such as toxic chemicals or radiation.

What is NBS disease?

Nijmegen breakage syndrome (NBS) is a rare autosomal recessive syndrome of chromosomal instability mainly characterized by microcephaly at birth, combined immunodeficiency and predisposition to malignancies.

What is Nbsld?

OMIMĀ® : 57 Nijmegen breakage syndrome-like disorder (NBSLD) is an autosomal recessive disorder characterized by severe prenatal growth retardation and persistent postnatal growth restriction, congenital microcephaly, borderline to mildly impaired intellectual development, normal sexual development, and radioresistant …

What causes Trichothiodystrophy?

What causes trichothiodystrophy? Trichothiodystrophy is caused by defective DNA repair and transcription and is inherited in an autosomal recessive pattern, meaning both parents must carry a copy of the mutated gene that causes trichothiodystrophy for a child to inherit the condition.

What does NBN gene do?

The NBN gene provides instructions for making a protein called nibrin. This protein is involved in several critical cellular functions, including the repair of damaged DNA. Nibrin interacts with two other proteins, produced from the MRE11A and RAD50 genes, as part of a larger protein complex.

What happens to the body with Bloom syndrome?

A rare, inherited disorder marked by shorter than average height, a narrow face, a red skin rash that occurs on sun-exposed areas of the body, and an increased risk of cancer. The rash usually occurs on the face, arms, and back of the hands.

What causes Roberts syndrome?

Roberts syndrome is caused by disruptions or changes of the ESCO2 (establishment of cohesion 1 homolog 2) gene located on the short arm (p) of chromosome 8 (8p21. 1). Chromosomes, which are present in the nucleus of human cells, carry the genetic information for each individual.

Can trichothiodystrophy be cured?

Given there is no cure for trichothiodystrophy, treatment is based around managing clinical manifestations, symptoms, and complications. Patients who are photosensitive should be provided with sun protection advice. Infections should be treated early and aggressively [1].

What is woolly hair?

Woolly hair is a rare congenital abnormality of the structure of the scalp hair characterized by tightly coiled hair involving part or the entire scalp occurring in an individual of non-negroid origin. [1] It was first observed and described by Gossage in 1907 in a European family.
