Variant summary

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

The NM_181426.2(CCDC39):c.233G>A(p.Arg78His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00647 in 1,552,978 control chromosomes in the GnomAD database, including 60 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/20 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. R78C) has been classified as Uncertain significance.

Genes affected

CCDC39 (HGNC:25244): (coiled-coil domain 39 molecular ruler complex subunit) The protein encoded by this gene is involved in the motility of cilia and flagella. The encoded protein is essential for the assembly of dynein regulatory and inner dynein arm complexes, which regulate ciliary beat. Defects in this gene are a cause of primary ciliary dyskinesia type 14 (CILD14). [provided by RefSeq, Jul 2011]

ACMG classification

Classification was made for transcript

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

BP4

Computational evidence support a benign effect (MetaRNN=0.0032339096).

BP6

Variant 3-180661985-C-T is Benign according to our data. Variant chr3-180661985-C-T is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 221189.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.00468 (713/152196) while in subpopulation SAS AF = 0.0183 (88/4820). AF 95% confidence interval is 0.0152. There are 5 homozygotes in GnomAd4. There are 358 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AR,AD gene
