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).

PreventionGenetics, part of Exact Sciences

Significance:Likely pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The RPGRIP1L c.3529C>T variant is predicted to result in premature protein termination (p.Arg1177*). This variant was reported in conjunction with a second RPGRIP1L variant in an individual with Joubert syndrome (Table S5. Bachmann-Gagescu et al. 2015. PubMed ID: 26092869). This variant was also identified in individuals with Meckel syndrome (Table S3. Hanany et al. 2020. PubMed ID: 31964843). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD. Nonsense variants in RPGRIP1L are expected to be pathogenic. This variant is interpreted as likely pathogenic. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3529C>T (p.R1177*) alteration, located in exon 24 (coding exon 23) of the RPGRIP1L gene, consists of a C to T substitution at nucleotide position 3529. This changes the amino acid from a arginine (R) to a stop codon at amino acid position 1177. This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. Based on data from gnomAD, the T allele has an overall frequency of <0.01% (4/251476) total alleles studied. The highest observed frequency was <0.01% (1/30616) of South Asian alleles. This variant was identified in one individual with Joubert syndrome in conjunction with a second RPGRIP1L variant (Bachmann-Gagescu, 2015). Based on the available evidence, this alteration is classified as pathogenic. -

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg1177*) 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 (rs778533826, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with clinical features of Joubert syndrome (PMID: 26092869). ClinVar contains an entry for this variant (Variation ID: 217694). For these reasons, this variant has been classified as Pathogenic. -
