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]

Dec 28, 2022

The c.596G>A (p.R199Q) alteration is located in exon 5 (coding exon 5) of the THEG gene. This alteration results from a G to A substitution at nucleotide position 596, causing the arginine (R) at amino acid position 199 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
