Variant summary

Our verdict is Benign. The variant received -10 ACMG points: 0P and 10B. BP4_ModerateBS1BS2

The NM_001206927.2(DNAH8):c.3215G>A(p.Arg1072Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000238 in 1,564,054 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1072W) has been classified as Uncertain significance.

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 -10 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.12315586).

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000238 (336/1411976) while in subpopulation MID AF = 0.00427 (24/5622). AF 95% confidence interval is 0.00294. There are 2 homozygotes in GnomAdExome4. There are 163 alleles in the male GnomAdExome4 subpopulation. Median coverage is 29. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR gene
