Since the traits for hemophilia are carried on the X chromosome and not the Y, it is more probable for females to have a chromosome with the mutation. Since the mutation is considered recessive and males only have one X chromosome, they are more likely to portray the phenotype for hemophilia than their female counterparts.
Marfan syndrome is caused by mutations in the FBN1 gene found on chromosome 15. This gene provides instructions for making a protein called fibrillin-1, which plays a role in the formation of connective tissue. People with Marfan syndrome have a defect in fibrillin-1, leading to issues in various body systems, including the skeletal, cardiovascular, and ocular systems.
Marfan syndrome is caused by mutations in the FBN1 gene on chromosome 15. The chromosme pattern is normal (44XY or 44XX), however see for discussion of a boy with XYY pattern and Marfan below:
No, the alleles for achondroplasia are not found on the sex chromosomes. The incidence is the same for both sexes.
If it was sex linked the ratio would be much higher in males and they would also essentially be
homozygous for the trait which would make the death toll in affected male babies 100%.
Yes, achondroplasia is a chromosomal disorder. The type of chromosomal disorder this is, is an autosomal- dominant.
Mutations that cause Marfan syndrome are found on FBN1 on chromosome 15. There are over 600 known mutations that cause Marfan; many families have a mutation that is unique to their family.
Marfan syndrome is caused by a single gene for fibrillin on chromosome 15, which is inherited in most cases from an affected parent.

What chromosome is affected by meckel syndrome?
Meckel Syndrome (type 1)is an autosomal recessive trait carried on chromosome 17.
What chromosome is affected in Turner Syndrome?
The chromosomes which are affected in Turner's Syndrome is the sex chromosomes. A normal female individual has 2 X sex chromosomes. In Turner's Syndrome, a woman only has one X chromosome and is missing the other. Thus, a woman with Turner's Syndrome has the sex chromosomes X0.
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.
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 can an extra chromosome do?
Having an extra chromosome, known as trisomy, can lead to genetic disorders such as Down syndrome (trisomy 21) or Edwards syndrome (trisomy 18). These disorders can affect physical and intellectual development, leading to characteristic features and health challenges. The specific impact of an extra chromosome varies depending on which chromosome is affected.
What chromosome pair is affected by marfan syndrome?
17
What is the etiology of marfan syndrome?
The etiology of marfan syndrome would be the mutations in the protein FBN1 in the gene chromosome 15.
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.
Is Down Syndrome the same as Marfan Syndrome?
No. Down is caused by an extra chromosome while Marfan is due to a mutation in one or more genes.
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.
Is marfan syndrome carried on the x or y chromosome or both?
Marfan syndrome is typically inherited in an autosomal dominant pattern, meaning that a mutation in a single copy of the gene is enough to cause the disorder. It is not specifically located on the X or Y chromosome.
What gene or chromosome is affected by down syndrome?
Chromosome 21 is tripled in Down syndrome.
What is the inheritance pattern to Marfan Syndrome?
Marfan syndrome is an autosomal dominant disorder. An affected person has a 50% chance of passing it on to each offspring, regardless of gender.
What chromosome is affected by Lobstein Syndrome?
13
What major organ systems are affected by Marfan syndrome?
Marfan syndrome affects three major organ systems of the body: the heart and circulatory system, the bones and muscles, and the eyes.
What chromosome is affected by meckel syndrome?
Meckel Syndrome (type 1)is an autosomal recessive trait carried on chromosome 17.
What are the chances of getting marfan syndrome?
Marfan syndrome is found in 1 in every 5,000 - 10,000 births. If one of your parents has Marfan syndrome, you have a 50% chance of having Marfan syndrome.
