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=-0.56).
• BP6: Variant 3-52368828-G-A is Benign according to our data. Variant chr3-52368828-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 478468.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=0.154 with no splicing effect.
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00333 (507/152308) while in subpopulation SAS AF= 0.00643 (31/4824). AF 95% confidence interval is 0.00465. There are 2 homozygotes in gnomad4. There are 252 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 2 AR gene
