The NCI study provides limited evidence of an increased risk of birth defects in the sons or daughters of women who were exposed prenatally to DES. An increased risk of ovarian cancer in the daughters of women exposed in utero was observed, but it was based on three cases of almost 800, so the finding is considered preliminary and requires ...
An H&E stain of tissue from a chromophobe renal cell carcinoma, the second-most common cancer associated with BHD. People over 20 years of age with BHD have an increased risk of developing slow-growing kidney tumors (chromophobe renal carcinoma and renal oncocytoma), kidney cysts, and possibly tumors in other organs and tissues.

Genetic causes of birth defects include inheritance of abnormal genes from the mother or the father, as well as new mutations in one of the germ cells that gave rise to the fetus. Male germ cells mutate at a much faster rate than female germ cells, and as the father ages, the DNA of the germ cells mutates quickly.
Other mutant alleles of the FH gene, located on human chromosome 1 at position 1q42.1, cause multiple cutaneous and uterine leiomyomata, hereditary leiomyomatosis and renal cell cancer. [5] Fumarase deficiency is one of the few known deficiencies of the Krebs cycle or tricarboxylic acid cycle, the main enzymatic pathway of cellular aerobic ...
Roberts syndrome, or sometimes called pseudothalidomide syndrome, is an extremely rare autosomal recessive genetic disorder that is characterized by mild to severe prenatal retardation or disruption of cell division, leading to malformation of the bones in the skull, face, arms, and legs.
It is believed to be caused by defects of genes on chromosome 3 and 18. One form of Seckel syndrome can be caused by mutation in the gene encoding the ataxia telangiectasia and Rad3-related protein which maps to chromosome 3q22.1–q24. This gene is central in the cell's DNA damage response and repair mechanism. Types include: [6]
Proteus syndrome is a rare genetic disorder [1] that can cause tissue overgrowth involving all three embryonic lineages. Patients with Proteus syndrome tend to have an increased risk of embryonic tumor development. [2] The clinical symptoms and radiographic findings of Proteus syndrome are highly variable, as are its orthopedic manifestations ...
Beckwith–Wiedemann syndrome (/ ˈ b ɛ k ˌ w ɪ θ ˈ v iː d ə. m ə n /; abbreviated BWS) is an overgrowth disorder usually present at birth, characterized by an increased risk of childhood cancer and certain congenital features. A minority (<15%) of cases of BWS are familial, meaning that a close relative may also have BWS, and parents ...
