Variant summary

Our verdict is Benign. The variant received -9 ACMG points: 0P and 9B. BP4_StrongBP6BS1

The NM_017802.4(DNAAF5):c.697G>A(p.Ala233Thr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000558 in 1,614,210 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A233S) 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 -9 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.013641149).

BP6

Variant 7-729764-G-A is Benign according to our data. Variant chr7-729764-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 410304.

BS1

Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.0000472 (69/1461872) while in subpopulation MID AF = 0.000867 (5/5768). AF 95% confidence interval is 0.000341. There are 0 homozygotes in GnomAdExome4. There are 31 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
