Genes affected

DNAH8 (HGNC:2952): (dynein axonemal heavy chain 8) The protein encoded by this gene is a heavy chain of an axonemal dynein involved in sperm and respiratory cilia motility. Axonemal dyneins generate force through hydrolysis of ATP and binding to microtubules. [provided by RefSeq, Jan 2012]

DNAH8-AS1 (HGNC:40188): (DNAH8 antisense RNA 1)

ACMG classification

Our verdict: Benign. The variant received -19 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.38).
• BP6: Variant 6-38935645-G-A is Benign according to our data. Variant chr6-38935645-G-A is described in ClinVar as Benign. ClinVar VariationId is 257627.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=1.3 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0219 (3339/152240) while in subpopulation NFE AF = 0.0322 (2188/68026). AF 95% confidence interval is 0.031. There are 52 homozygotes in GnomAd4. There are 1660 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High Homozygotes in GnomAd4 at 52 AR gene
