Genes affected

SPO11 (HGNC:11250): (SPO11 initiator of meiotic double strand breaks) Meiotic recombination and chromosome segregation require the formation of double-strand breaks (DSBs) in paired chromosome homologs. During meiosis in yeast, a meiotic recombination protein is covalently-linked to the 5' end of DSBs and is essential for the formation of DSBs. The protein encoded by this gene is similar in sequence and conserved features to the yeast meiotic recombination protein. The encoded protein belongs to the TOP6A protein family. Several transcript variants encoding different isoforms have been found for this gene, but the full-length nature of only two of them have been described. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.169G>A (p.D57N) alteration is located in exon 2 (coding exon 2) of the SPO11 gene. This alteration results from a G to A substitution at nucleotide position 169, causing the aspartic acid (D) at amino acid position 57 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
