Description : Testicular germ cell tumors (TGCTs) affect 1 in 500 men and are the most common cancer
in males aged 15 to 40 in western European populations. The incidence of TGCT rose
dramatically during the 20th century. Known risk factors for TGCT include a history
of undescended testis (UDT), testicular dysgenesis, infertility, previously diagnosed
TGCT, and a family history of the disease. Brothers of men with TGCT have an 8- to
10-fold risk of developing TGCT, whereas the relative risk to fathers and sons is
4-fold. This familial relative risk is much higher than that for most other types
of cancer (summary by Rapley et al., 2000). - Genetic Heterogeneity of Testicular
Germ Cell Tumors A locus for testicular germ cell tumors (TGCT1; 300228) has been
identified on chromosome Xq27.;
Inheritance : Somatic mutation;
Neoplasia : Male germ cell tumors (GCT), 2 subtypes -; Seminoma; Nonseminoma (embryonal carcinoma, teratoma, choriocarcinoma, endodermal sinus tumor);
Laboratory abnormalities : Isochromosome 12p (i(12p)); Elevated hCG or AFP or both (embryonal carcinoma); Elevated AFP (endodermal sinus tumor); Elevated hCG (choriocarcinoma); Azoospermia/oligospermia (present at diagnosis);
