RCV000539991 | SCV000623954 | pathogenic | Primary ciliary dyskinesia | 2023-10-14 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Gln451*) in the RSPH4A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RSPH4A are known to be pathogenic (PMID: 19200523). This variant is present in population databases (rs750528020, gnomAD 0.006%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 23993197). ClinVar contains an entry for this variant (Variation ID: 454520). For these reasons, this variant has been classified as Pathogenic. |

Ambry Genetics | RCV000539991 | SCV005489336 | pathogenic | Primary ciliary dyskinesia | 2024-07-10 | criteria provided, single submitter | clinical testing | The p.Q451* pathogenic mutation (also known as c.1351C>T), located in coding exon 3 of the RSPH4A gene, results from a C to T substitution at nucleotide position 1351. This changes the amino acid from a glutamine to a stop codon within coding exon 3. This variant has been identified in conjunction with another RSPH4A variant in an individual with features consistent with primary ciliary dyskinesia and axonemal defects confirmed by transmission electronic microscopy (Kott E et al. Am J Hum Genet, 2013 Sep;93:561-70). 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. |
