ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DNHD1. . Gene score misZ 3.4791 (greater than the threshold 3.09). Trascript score misZ 3.2933 (greater than threshold 3.09). GenCC has associacion of gene with spermatogenic failure 65.
BP4
Computational evidence support a benign effect (MetaRNN=0.03834954).

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.67T>A (p.W23R) alteration is located in exon 3 (coding exon 1) of the DNHD1 gene. This alteration results from a T to A substitution at nucleotide position 67, causing the tryptophan (W) at amino acid position 23 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
