Genes affected

DNAH1 (HGNC:2940): (dynein axonemal heavy chain 1) This gene encodes an inner dynein arm heavy chain that provides structural support between the radial spokes and the outer doublet of the sperm tail. Naturally occurring mutations in this gene are associated with primary ciliary dyskinesia and multiple morphological anomalies of the flagella that result in asthenozoospermia and male infertility. Mice with a homozygous knockout of the orthologous gene are viable but have reduced sperm motility and are infertile. [provided by RefSeq, Feb 2017]

ACMG classification

Verdict is Benign. Variant got -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.71).
• BP6: Variant 3-52353186-G-A is Benign according to our data. Variant chr3-52353186-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 478438.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-52353186-G-A is described in Lovd as [Likely_benign].
• BP7: Synonymous conserved (PhyloP=-3.74 with no splicing effect.
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00416 (634/152318) while in subpopulation NFE AF= 0.00728 (495/68028). AF 95% confidence interval is 0.00675. There are 0 homozygotes in gnomad4. There are 278 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAdExome4 at 67 AR gene
