hypospadias/아르기닌

OBJECTIVE To identify possible molecular mechanism underlined hypospadias and any relationship of the mutations of SRD5A2 gene and SRY gene to hypospadias. METHODS Twenty-three blood samples from the patients with hypospadias were obtained from Aug.1996 to Jan. 1998. DNA was extracted from blood

Testicular disorder of sex development (TDSD) is a rare condition, characterised by a female karyotype, male phenotype, small testes and cryptorchidism. Only a few studies have investigated the genetic causes of male sex reversal. This is the clinical report of an Iranian 46,XX patient presented

Mutations of the androgen receptor gene causing androgen insensitivity syndrome in 46, XY individuals, result in phenotypes ranging from complete female to ambiguous genitalia to males with minor degrees of undervirilization. We studied two Brazilian brothers with partial androgen insensitivity

We report the case of an infant who presented at birth with a hypoplastic phallus associated with hypospadias. Low testosterone production, normal serum levels of steroid precursors, and increased LH in response to LH-releasing hormone supported a defect in Leydig cell differentiation or function.

OBJECTIVE To analyze the steroid 5-alpha reductase type 2 gene (SRD5A2) in 2 siblings with severe male pseudohermaphroditism suspected to have 5-alpha reductase deficiency in a Turkish family. METHODS Two female siblings of a family with 7 children were referred to the urology department because of

The androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resemble males. The primary abnormality is a defective androgen receptor protein due to a mutation of the androgen
