Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_024532.5(SPAG16):​c.1527+38601A>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.803 in 152,114 control chromosomes in the GnomAD database, including 49,493 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.80 (49493 hom., cov: 32)
• Consequence: SPAG16 NM_024532.5 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -2.96

Genes affected

SPAG16 (HGNC:23225): (sperm associated antigen 16) Cilia and flagella are comprised of a microtubular backbone, the axoneme, which is organized by the basal body and surrounded by plasma membrane. SPAG16 encodes 2 major proteins that associate with the axoneme of sperm tail and the nucleus of postmeiotic germ cells, respectively (Zhang et al., 2007 [PubMed 17699735]).[supplied by OMIM, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.0).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.875 is higher than 0.05.
