- Leydig cell tumor [DOID:2696]
A sex cord-gonadal stromal tumor that secretes testosterone characterized by excessive proliferation of Leydig cells located_in ovary or testicle.
- Sertoli-Leydig cell tumor [DOID:2997]
A sex cord-gonadal stromal tumor characterized by variable proportions of Sertoli cells, Leydig cells, primitive gonadal stroma and/or heterologous elements located_in the ovaries and testicles.
- sex cord-gonadal stromal tumor [DOID:192]
A reproductive organ cancer that is located_in the sex cord-derived tissues of the ovary or testis and derives_from granulosa cells, Leydig cells, Sertoli cells, and fibroblasts.
- Leydig cell hypoplasia type II [DOID:0112261]
A Leydig cell hypoplasia characterized by variable features ranging from micropenis to severe hypospadias and bifid scrotum that has_material_basis_in homozygous or compound heterozygous partial inactivation mutation in the LHCGR gene on chromosome 2p16.3.
- Leydig cell hypoplasia type I [DOID:0112260]
A Leydig cell hypoplasia characterized by 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 that has_material_basis_in homozygous or compound heterozygous complete inactivation mutation in the LHCGR gene on chromosome 2p16.3.
- DICER1 syndrome [DOID:0081063]
A syndrome that is characterized by an increased risk of developing pleuropulmonary blastoma, multinodular goiter, ovarian Sertoli-Leydig cell tumors, and/or other types of tumors, and that has_material_basis_in heterozygous mutation in the DICER1 gene on chromosome 14q32. Mutations of the gene encoding the endoribonuclease, Dicer, disrupts the biogenesis and processing of miRNAs with subsequent disruption in control of gene expression.
