Genes affected
TNP2 (HGNC:11952): (transition protein 2) Predicted to enable zinc ion binding activity. Predicted to be involved in positive regulation of protein processing; single fertilization; and spermatogenesis, exchange of chromosomal proteins. Predicted to act upstream of or within binding activity of sperm to zona pellucida and flagellated sperm motility. Predicted to be located in nucleus. Predicted to be part of nucleosome. [provided by Alliance of Genome Resources, Apr 2022]
RMI2 (HGNC:28349): (RecQ mediated genome instability 2) RMI2 is a component of the BLM (RECQL3; MIM 604610) complex, which plays a role in homologous recombination-dependent DNA repair and is essential for genome stability (Xu et al., 2008 [PubMed 18923082]).[supplied by OMIM, Nov 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.209G>C (p.S70T) alteration is located in exon 1 (coding exon 1) of the TNP2 gene. This alteration results from a G to C substitution at nucleotide position 209, causing the serine (S) at amino acid position 70 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
