Genes affected

NANOS1 (HGNC:23044): (nanos C2HC-type zinc finger 1) This gene encodes a CCHC-type zinc finger protein that is a member of the nanos family. This protein co-localizes with the RNA-binding protein pumilio RNA-binding family member 2 and may be involved in regulating translation as a post-transcriptional repressor. Mutations in this gene are associated with spermatogenic impairment. [provided by RefSeq, Sep 2015]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3179081).

The c.274G>A (p.G92R) alteration is located in exon 1 (coding exon 1) of the NANOS1 gene. This alteration results from a G to A substitution at nucleotide position 274, causing the glycine (G) at amino acid position 92 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
