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]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.016131371).

BP6

Variant 6-38781288-C-G is Benign according to our data. Variant chr6-38781288-C-G is described in ClinVar as Likely_benign. ClinVar VariationId is 407294.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00164 (249/152216) while in subpopulation NFE AF = 0.00315 (214/68010). AF 95% confidence interval is 0.0028. There are 1 homozygotes in GnomAd4. There are 97 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 8 AR gene
