Genes affected
TNP1 (HGNC:11951): (transition protein 1) Transition protein-1 is a spermatid-specific product of the haploid genome which replaces histone and is itself replaced in the mature sperm by the protamines (see PRM1, MIM 182880; PRM2, MIM 182890) (Luerssen et al., 1990 [PubMed 2249851]).[supplied by OMIM, Mar 2008]
TESHL (HGNC:52740): (testicular germ cell expressed HSF2 interacting lncRNA)
DIRC3-AS1 (HGNC:50636): (DIRC3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2024The c.13C>G (p.R5G) alteration is located in exon 1 (coding exon 1) of the TNP1 gene. This alteration results from a C to G substitution at nucleotide position 13, causing the arginine (R) at amino acid position 5 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
