Based on the classification scheme VCGS_Germline_v1.3.4, this variant is classified as Pathogenic. Following criteria are met: 0102 - Loss of function is a known mechanism of disease in this gene and is associated with primary ciliary dyskinesia 3, with or without situs inversus (PCD; MIM#608644). (I) 0106 - This gene is associated with autosomal recessive disease. (I) 0201 - Variant is predicted to cause nonsense-mediated decay (NMD) and loss of protein (premature termination codon is located at least 54 nucleotides upstream of the final exon-exon junction). (SP) 0251 - This variant is heterozygous. (I) 0304 - Variant is present in gnomAD <0.01 for a recessive condition (v2: 45 heterozygotes, 1 homozygote). (SP) 0701 - Other NMD variants comparable to the one identified in this case have very strong previous evidence for pathogenicity (ClinVar, DECIPHER). (SP) 0801 - This variant has very strong previous evidence of pathogenicity in unrelated individuals. It has been reported in multiple families with primary ciliary dyskinesia (ClinVar, LOVD, PMIDs: 29363216, 16627867, 23477994). (SP) 1205 - This variant has been shown to be maternally inherited (by segregation analysis). (I) Legend: (SP) - Supporting pathogenic, (I) - Information, (SB) - Supporting benign -

c.10815delT in DNAH5 has been identified in multiple unrelated individuals as well as families with primary ciliary dyskinesia and is a known North American founder mutation. This frameshift variant (rs397515540) has been reported in ClinVar (Variation ID 65636) and is rare (<0.1%) in a large population dataset (gnomAD v2.1.1: 47/282304 total alleles; 0.0167%; 1 homozygote). This frameshift variant results in a premature stop codon in exon 64 of 79, likely leading to nonsense-mediated decay and lack of protein production. We consider c.10815delT; p.Pro3606fs in DNAH5 to be pathogenic. -
The DNAH5 c.10815delT (p.Pro3606HisfsTer23) variant results in a frameshift and is predicted to result in premature termination of the protein. The p.Pro3606HisfsTer23 variant has been reported in a total of 17 individuals with primary ciliary dyskinesia, including in two in a homozygous state and in 15 in a compound heterozygous state (Hornef et al. 2006; Djakow et al. 2012; Ferkol et al. 2013; Kim et al. 2014; Raidt et al. 2014). The p.Pro3606HisfsTer23 variant was found to segregate with disease where familial DNA was available, and haplotype analysis revealed this variant is a founder mutation (Hornef et al. 2006). The p.Pro3606HisfsTer23 variant was absent from 70 controls and is reported at a frequency of 0.00024 in the European (non-Finnish) population of the Exome Aggregation Consortium. Based on the evidence and potential impact of frameshift variants, the p.Pro3606HisfsTer23 variant is classified as pathogenic for primary ciliary dyskinesia. This variant was observed by ICSL as part of a predisposition screen in an ostensibly healthy population. -

The c.10815delT pathogenic mutation, located in coding exon 63 of the DNAH5 gene, results from a deletion of one nucleotide at nucleotide position 10815, causing a translational frameshift with a predicted alternate stop codon (p.P3606Hfs*23). In one study, this mutation was seen in 7 of 134 (5.2%) primary ciliary dyskinesia (PCD) families, with a particularly high prevalence in individuals with PCD from the United States (Hornef N et al. Am. J. Respir. Crit. Care Med., 2006 Jul;174:120-6). In addition to the clinical data presented in the literature, this alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. -
This sequence change creates a premature translational stop signal (p.Pro3606Hisfs*23) in the DNAH5 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in DNAH5 are known to be pathogenic (PMID: 11788826, 16627867). This variant is present in population databases (rs397515540, gnomAD 0.03%), including at least one homozygous and/or hemizygous individual. This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 16627867, 22416021, 23477994, 24498942). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 65636). For these reasons, this variant has been classified as Pathogenic. -

This sequence change in DNAH5 is a frameshift variant predicted to cause a premature stop codon, p.(Pro3606Hisfs*23), in biologically relevant exon 64/79 leading to nonsense-mediated decay in a gene in which loss of function is an established disease mechanism. The highest population minor allele frequency in the population database gnomAD v4.0 is 0.05% (638/1,179,900 alleles) in the European (non-Finnish) population. This variant is a North American founder mutation that has been detected in the homozygous and compound heterozygous state in multiple individuals with primary ciliary dyskinesia (PCD), confirmed in trans in at least one individual (PMID: 16627867, 29363216). It segregates with PCD in at least one family (PMID: 16627867). Based on the classification scheme RMH Modified ACMG/AMP Guidelines v1.6.1, this variant is classified as PATHOGENIC. Following criteria are met: PVS1, PM3_VeryStrong, PP1. -
