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]

Ambry Genetics

Sep 29, 2023

The c.133G>A (p.D45N) alteration is located in exon 1 (coding exon 1) of the TNP1 gene. This alteration results from a G to A substitution at nucleotide position 133, causing the aspartic acid (D) at amino acid position 45 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
