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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.014879525).
BP6
Variant 6-38938181-C-T is Benign according to our data. Variant chr6-38938181-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 402771.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00663 (1009/152274) while in subpopulation AFR AF = 0.00917 (381/41552). AF 95% confidence interval is 0.00841. There are 7 homozygotes in GnomAd4. There are 486 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 7 AR gene
