Noonan syndrome is primarily caused by mutations in the PTPN11 gene, located on chromosome 12. This gene provides instructions for making a protein involved in cell signaling and development. Changes in this gene can disrupt normal cell signaling pathways and lead to the characteristic features of Noonan syndrome.

What gene is affected by Barth syndrome?
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
What chromosome is gene located for marfan syndrome?
The gene associated with Marfan syndrome is located on chromosome 15. It is called the FBN1 gene, which provides instructions for making a protein called fibrillin-1. Mutations in this gene can lead to the characteristic features of Marfan syndrome.
What are the causes of Noonan syndrome?
Noonan syndrome is usually caused by genetic mutations that affect proteins involved in signaling pathways that regulate cell growth and development. Most cases are sporadic, but some can be inherited in an autosomal dominant pattern. Mutations in genes such as PTPN11, SOS1, and RAF1 have been associated with Noonan syndrome.
Why does Lesch-Nyhan syndrome affect males?
Lesch-Nyhan syndrome is an X-linked recessive disorder, meaning the gene mutation responsible for the condition is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if they inherit the mutated gene on their X chromosome, they will develop the disorder. Females have two X chromosomes, so they are less likely to inherit the mutation on both X chromosomes.
Dose marfan syndrome have to be on a x chormose?
Marfan syndrome is caused by a mutation in the FBN1 gene, which is located on chromosome 15 and is inherited in an autosomal dominant pattern. It is not linked to the X chromosome. Both males and females can inherit and display symptoms of Marfan syndrome.
What gene or chromosome is affected by down syndrome?
Chromosome 21 is tripled in Down syndrome.
What gene is affected in prader willi syndrome?
if you mean chromosome its the 15th......
What gene is affected by Barth syndrome?
Barth syndrome occurs when a person is born with a mutated, or abnormal, TAZ1 (or G4.5) gene. This abnormal gene is located on the X chromosome, which is a sex-determining chromosome. Males have one X and one Y chromosome, while females have two X chromosomes.
What chromosome number is affected in Lowe syndrome?
Lowe syndrome is caused by a mutated gene on the X sex chromosome. Because it is X-linked, it occurs almost exclusively in males.
Which chromosome is affected in Rubinstein-Taybi syndrome?
Rubinstein-Taybi syndrome is caused by a non-functional copy of the BREP binding protein gene (either by mutation or deletion) on chromosome 16.
How many chromosome do you have when you have fragile x syndrome?
Fragile X syndrome is caused by a mutation that prevents the Fragile X mental retardation (Fmr-1) gene from being transcribed. This gene is located on the X chromosome (the sex chromosome). Since males only carry one of these chromosomes, they are twice as likely to be affected by the mutation than females.
What gene is affected in Down Syndrome?
It is the result of a chromosomal abnormality, in which there is an extra chromsome on the chromosome 21 pair. This is call trisomy 21.
What gene or chromosome is affected by Crouzon Syndrome disorder?
Crouzon Syndrome is caused by mutations in the FGFR2 gene, which is located on chromosome 10. These mutations disrupt the function of the FGFR2 protein, leading to abnormal development of the skull and face.
Is there a gene or chromosome affected by anemia?
Obviously.
What chromosome is gene located for marfan syndrome?
The gene associated with Marfan syndrome is located on chromosome 15. It is called the FBN1 gene, which provides instructions for making a protein called fibrillin-1. Mutations in this gene can lead to the characteristic features of Marfan syndrome.
What chromosomes are affected with hurler syndrome?
Hurler syndrome is caused by a mutation in the gene located on chromosome 4 that provides instructions for producing an enzyme called alpha-L-iduronidase. This mutation leads to the accumulation of glycosaminoglycans in the body, resulting in the various symptoms associated with the syndrome.
What gene is affected by type 1 diabetes?
Chromosome 2
