Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_017802.4(DNAAF5):c.921C>A(p.Ser307Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0147 in 1,588,566 control chromosomes in the GnomAD database, including 229 homozygotes. In-silico tool predicts a benign outcome for this variant. 15/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S307T) has been classified as Uncertain significance.

Genes affected

DNAAF5 (HGNC:26013): (dynein axonemal assembly factor 5) The protein encoded by this gene is essential for the preassembly or stability of axonemal dynein arms, and is found only in organisms with motile cilia and flagella. Mutations in this gene are associated with primary ciliary dyskinesia-18, a disorder characterized by abnormalities of motile cilia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Feb 2013]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.004960537).

BP6

Variant 7-741362-C-A is Benign according to our data. Variant chr7-741362-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 241211.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 = 0.0132 (2006/152338) while in subpopulation NFE AF = 0.0199 (1352/68030). AF 95% confidence interval is 0.019. There are 23 homozygotes in GnomAd4. There are 1001 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 23 AR,AD gene
