Bloom syndrome is an autosomal recessive disorder, caused by mutations in the maternally- and paternally-derived copies of the gene BLM. [13] As in other autosomal recessive conditions, the parents of an individual with Bloom syndrome do not necessarily exhibit any features of the syndrome.

But elimination of any gene essential for base excision repair kills the embryo—it is too lethal to display symptoms (much less symptoms of cancer or "accelerated aging"). [38] Rothmund-Thomson syndrome and xeroderma pigmentosum display symptoms dominated by vulnerability to cancer, whereas progeria and Werner syndrome show the most features ...
The diagnosis is made either by testing of the fumarate hydratase activity in cultured skin fibroblasts or lymphoblastoid cells and demonstrating reduced activity (≤60%) or by molecular genetic testing. [3] Special histologic features of fibroids may allow an early diagnosis in absence of other symptoms. [4]
NBS is caused by a mutation in the NBS1 gene, located at human chromosome 8q21. [9] [10] The disease is inherited in an autosomal recessive manner. [2]This means the defective gene responsible for the disorder is located on an autosome (chromosome 8 is an autosome), and two copies of the defective gene (one inherited from each parent) are required in order to be born with the disorder.

Mismatch repair cancer syndrome (MMRCS) is a cancer syndrome associated with biallelic DNA mismatch repair mutations. [1] It is also known as Turcot syndrome (after Jacques Turcot, who described the condition in 1959) and by several other names. [1] In MMRCS, neoplasia typically occurs in both the gut and the central nervous system (CNS). [1]
CKM syndrome, a cluster of conditions that may lead to heart disease, may affect 90% of U.S. adults. Doctors explain cardiovascular-kidney-metabolic syndrome.
