GENE - TERM ANNOTATION REPORT

RGD ID: 732291
Species: Mus musculus
RGD Object: Gene
Symbol: Fgfr1
Name: fibroblast growth factor receptor 1
Acc ID: DOID:1921
Term: Klinefelter's syndrome
Definition: A form of male HYPOGONADISM, characterized by the presence of an extra X CHROMOSOME, small TESTES, seminiferous tubule dysgenesis, elevated levels of GONADOTROPINS, low serum TESTOSTERONE, underdeveloped secondary sex characteristics, and male infertility (INFERTILITY, MALE). Patients tend to have long legs and a slim, tall stature. GYNECOMASTIA is present in many of the patients. The classic form has the karyotype 47,XXY. Several karyotype variants include 48,XXYY; 48,XXXY; 49,XXXXY, and mosaic patterns ( 46,XY/47,XXY; 47,XXY/48,XXXY, etc.).
