A disgenesia gonadal 46,XX (DG 46,XX) é um problema primário nos ovários que leva à falência ovariana prematura (FOP), também conhecida como menopausa precoce, em mulheres com cromossomos 46,XX que, de outra forma, seriam normais. Isso acontece porque os ovários não se desenvolvem ou porque não respondem aos hormônios (gonadotrofinas) que deveriam estimulá-los.

Nephrotic syndrome 11
A form of nephrotic syndrome, a renal disease clinically characterized by severe proteinuria, resulting in complications such as hypoalbuminemia, hyperlipidemia and edema. Kidney biopsies show non-specific histologic changes such as focal segmental glomerulosclerosis and diffuse mesangial proliferation. Some affected individuals have an inherited steroid-resistant form and progress to end-stage renal failure. NPHS11 is an autosomal recessive, steroid-resistant and progressive form with onset in the first decade of life.

Transcriptional activator (By similarity). It is likely involved in the regulation of keratinocytes terminal differentiation in squamous epithelia and hair follicles (PubMed:8034748). Required for the maintenance of spermatogenesis (By similarity). It is involved in the positive regulation of oocyte maturation, probably acting through the control of BMP15 levels and regulation of AKT signaling cascade (PubMed:30010909).

Premature ovarian failure 16
An autosomal dominant form of premature ovarian failure, an ovarian disorder defined as the cessation of ovarian function under the age of 40 years. It is characterized by oligomenorrhea or amenorrhea, in the presence of elevated levels of serum gonadotropins and low estradiol.
Germline specific transcription factor implicated in postnatal oocyte-specific gene expression. Plays a key regulatory role in the expression of multiple oocyte-specific genes, including those that initiate folliculogenesis and those that encode the zona pellucida (ZP1, ZP2 and ZP3) required for fertilization and early embryonic survival. Essential for oocytes to survive and form primordial follicles. The persistence of FIGLA in adult females suggests that it may regulate additional pathways tha
