Genes affected

RPGRIP1L (HGNC:29168): (RPGRIP1 like) The protein encoded by this gene can localize to the basal body-centrosome complex or to primary cilia and centrosomes in ciliated cells. The encoded protein has been found to interact with nephrocystin-4. Defects in this gene are a cause of Joubert syndrome type 7 (JBTS7) and Meckel syndrome type 5 (MKS5).

Labcorp Genetics (formerly Invitae), Labcorp

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change creates a premature translational stop signal (p.Gln684*) in the RPGRIP1L gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in RPGRIP1L are known to be pathogenic (PMID: 17558409). This variant is present in population databases (rs121918204, gnomAD 0.01%). This premature translational stop signal has been observed in individuals with RPGRIP1L-related disease (PMID: 17558407, 21866095, 26092869). ClinVar contains an entry for this variant (Variation ID: 1076). For these reasons, this variant has been classified as Pathogenic. -
