It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CTSK are known to be pathogenic (PMID: 12125807, 21569238). This variant is present in population databases (rs74315303, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with pycnodysostosis (PMID: 8703060, 8938428). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 8422). For these reasons, this variant has been classified as Pathogenic.

Neuberg Supratech Reference Laboratories Pvt Ltd, Neuberg Centre for Genomic Medicine RCV000008933 SCV004100633 pathogenic Pyknodysostosis criteria provided, single submitter clinical testing The stop gained p.R241* in CTSK (NM_000396.4) has been observed in individuals affected with pycnodysostosis, and has been shown to segregate with disease in a family (B D Gelb et al; M R Johnson). It is expected to result in an absent or disrupted protein product. The variant has been reported to ClinVar as Pathogenic/Likely Pathogenic. This variant is predicted to cause loss of normal protein function through protein truncation. For these reasons, this variant has been classified as Pathogenic.
