Genes affected

THEG (HGNC:):

THEG links:

SPMAP2 (HGNC:13706): (sperm microtubule associated protein 2) This gene is specifically expressed in the nucleus of haploid male germ cells. The orthologous gene in mice encodes a protein that may play a role in protein assembly through interactions with T-complex protein 1 subunit epsilon. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]

The c.835A>C (p.T279P) alteration is located in exon 7 (coding exon 7) of the THEG gene. This alteration results from a A to C substitution at nucleotide position 835, causing the threonine (T) at amino acid position 279 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
