Summaries for Leydig Cell Hypoplasia, Type I

OMIM : 57 Leydig cell hypoplasia is an autosomal recessive disorder in which loss of function of the LHCGR gene in the male prevents normal sexual development. Two types of LCH have been defined (Toledo, 1992). Type I, a severe form caused by complete inactivation of LHCGR, is characterized by complete 46,XY male pseudohermaphroditism, low testosterone and high LH levels, total lack of responsiveness to LH/CG challenge, lack of breast development, and absent development of secondary male sex characteristics. Type II, a milder form caused by partial inactivation of the gene, displays a broader range of phenotypic expression ranging from micropenis to severe hypospadias. Females with inactivating mutations in the LHCGR gene display a mild phenotype characterized by defective follicular development and ovulation, amenorrhea, and infertility (review by Themmen and Huhtaniemi, 2000). (238320)

MalaCards based summary : Leydig Cell Hypoplasia, Type I, also known as luteinizing hormone resistance, female, is related to leydig cell hypoplasia and alzheimer disease. An important gene associated with Leydig Cell Hypoplasia, Type I is LHCGR (Luteinizing Hormone/Choriogonadotropin Receptor). Affiliated tissues include uterus, and related phenotypes are increased circulating gonadotropin level and hypergonadotropic hypogonadism

UniProtKB/Swiss-Prot : 75 Luteinizing hormone resistance: An autosomal recessive disorder characterized by unresponsiveness to luteinizing hormone, defective sexual development in males, and defective follicular development and ovulation, amenorrhea and infertility in females. Two forms of the disorder have been defined in males. Type 1 is a severe form characterized by complete 46,XY male pseudohermaphroditism, low testosterone and high luteinizing hormone levels, total lack of responsiveness to luteinizing and chorionic gonadotropin hormones, lack of breast development, and absent development of secondary male sex characteristics. Type 2, a milder form, displays a broader range of phenotypic expression ranging from micropenis to severe hypospadias.
