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).

This sequence change creates a premature translational stop signal (p.Arg805*) 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 (rs145665129, gnomAD 0.009%). This premature translational stop signal has been observed in individual(s) with Joubert syndrome (PMID: 19574260). ClinVar contains an entry for this variant (Variation ID: 1079). For these reasons, this variant has been classified as Pathogenic. -
