This sequence change creates a premature translational stop signal (p.Arg145*) in the C11orf70 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in C11orf70 are known to be pathogenic (PMID: 29727692, 29727693). This variant is present in population databases (rs754773453, gnomAD 0.004%). This premature translational stop signal has been observed in individual(s) with primary ciliary dyskinesia (PMID: 29727693). ClinVar contains an entry for this variant (Variation ID: 549861). For these reasons, this variant has been classified as Pathogenic. -
