Genes affected

NOBOX (HGNC:22448): (NOBOX oogenesis homeobox) This homeobox gene encodes a transcription factor that is thought to play a role in oogenesis. In mice, it is essential for folliculogenesis and regulation of oocyte-specific genes. Defects in this gene result in premature ovarian failure type 5.[provided by RefSeq, May 2011]

The c.1864G>A (p.D622N) alteration is located in exon 10 (coding exon 10) of the NOBOX gene. This alteration results from a G to A substitution at nucleotide position 1864, causing the aspartic acid (D) at amino acid position 622 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
