Genes affected

SPACA6-AS1 (HGNC:49383): (SPACA6 antisense RNA 1)

SPACA6 (HGNC:27113): (sperm acrosome associated 6) Predicted to be involved in fusion of sperm to egg plasma membrane involved in single fertilization. Predicted to be located in acrosomal vesicle. [provided by Alliance of Genome Resources, Apr 2022]

MIR125A (HGNC:31505): (microRNA 125a) microRNAs (miRNAs) are short (20-24 nt) non-coding RNAs that are involved in post-transcriptional regulation of gene expression in multicellular organisms by affecting both the stability and translation of mRNAs. miRNAs are transcribed by RNA polymerase II as part of capped and polyadenylated primary transcripts (pri-miRNAs) that can be either protein-coding or non-coding. The primary transcript is cleaved by the Drosha ribonuclease III enzyme to produce an approximately 70-nt stem-loop precursor miRNA (pre-miRNA), which is further cleaved by the cytoplasmic Dicer ribonuclease to generate the mature miRNA and antisense miRNA star (miRNA*) products. The mature miRNA is incorporated into a RNA-induced silencing complex (RISC), which recognizes target mRNAs through imperfect base pairing with the miRNA and most commonly results in translational inhibition or destabilization of the target mRNA. The RefSeq represents the predicted microRNA stem-loop. [provided by RefSeq, Sep 2009]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00912 (1387/152040) while in subpopulation AFR AF = 0.0312 (1296/41474). AF 95% confidence interval is 0.0298. There are 16 homozygotes in GnomAd4. There are 639 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 16 gene
