Genes affected
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 16, 2021The c.974A>T (p.D325V) alteration is located in exon 8 (coding exon 8) of the THEG gene. This alteration results from a A to T substitution at nucleotide position 974, causing the aspartic acid (D) at amino acid position 325 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
