Variant summary
Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The NM_001369.3(DNAH5):c.11869G>A(p.Asp3957Asn) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000031 in 1,613,888 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/22 in silico tools predict 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. D3957G) has been classified as Uncertain significance.

not specified Uncertain:1
The p.Asp3957Asn variant in DNAH5 has not been previously reported in individual s with PCD, but has been identified in 2/246028 of chromosomes by the Genome Agg regation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs749548708). Computational prediction tools and conservation analysis suggest that the p.Asp 3957Asn variant may not impact the protein, though this information is not predi ctive enough to rule out pathogenicity. In summary, the clinical significance of the p.Asp3957Asn variant is uncertain. ACMG/AMP Criteria applied: PM2; BP4. -
Primary ciliary dyskinesia Uncertain:1
This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 3957 of the DNAH5 protein (p.Asp3957Asn). This variant is present in population databases (rs749548708, gnomAD 0.003%). This variant has not been reported in the literature in individuals affected with DNAH5-related conditions. ClinVar contains an entry for this variant (Variation ID: 506280). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt DNAH5 protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
