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]

Aug 15, 2023

The c.1033C>T (p.R345C) alteration is located in exon 8 (coding exon 8) of the THEG gene. This alteration results from a C to T substitution at nucleotide position 1033, causing the arginine (R) at amino acid position 345 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
