Summary: This gene encodes a protein that functions in postnatal oocyte-specific gene expression. The protein is a basic helix-loop-helix transcription factor that regulates multiple oocyte-specific genes, including genes involved in folliculogenesis and those that encode the zona pellucida. Mutations in this gene cause premature ovarian failure type 6. [provided by RefSeq, Sep 2009]

What's a GeneRIF?

Our results support the notion that bi-allelic recessive loss-of-function effects of FIGLA contribute to POI patients with short stature and expand the FIGLA-related phenotypic spectrum.
Title: Bi-allelic recessive loss-of-function mutations in FIGLA cause premature ovarian insufficiency with short stature.
Biallelic mutations in FIGLA may be the cause of premature ovarian insufficiency (POI) . This study will aid researchers and clinicians in genetic counseling of POI and provides new insights into understanding the mode of genetic inheritance of FIGLA mutations in POI pathology.
Title: Consanguineous familial study revealed biallelic FIGLA mutation associated with premature ovarian insufficiency.
study identified an association between FIGLA gene variants and the occurrence of premature ovarian failure(POF) in the Indian population; findings suggest that the c.427G->C and c.557C->T alleles lead to an increased risk of POF in Indian women
Title: Mutational analysis of the FIGLA gene in women with idiopathic premature ovarian failure.
may have a role in the development of primordial follicle before zona pellucida formation
Title: Zona pellucida components are present in human fetal ovary before follicle formation.
the p.140 delN mutation disrupted FIGLA binding to the TCF3 helix-loop-helix (HLH) domain. Our findings show that a subset of Chinese women with sporadic, premature ovarian failure harbor mutations in FIGLA.
Title: Transcription factor FIGLA is mutated in patients with premature ovarian failure.
These results suggest that FIGLA is involved in continued oocyte survival as primordial follicles form in the human as in the rodent ovary.
Title: Increased expression of the FIGLA transcription factor is associated with primordial follicle formation in the human fetal ovary.
Expression of mRNA observed in ovarian follicles, mature oocytes, and less frequently in preimplantation embryos.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
