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.1931C>T (p.A644V) alteration is located in exon 10 (coding exon 10) of the NOBOX gene. This alteration results from a C to T substitution at nucleotide position 1931, causing the alanine (A) at amino acid position 644 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
