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).

Significance:Pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The RPGRIP1L c.2614C>T variant is predicted to result in premature protein termination (p.Gln872*). This variant has been reported together with another truncating variant in a fetus with phenotypic features consistent with Meckel-Gruber syndrome (Delous et al. 2007. PubMed ID: 17558409). This variant is reported in 0.0044% of alleles in individuals of European (Non-Finnish) descent in gnomAD. Nonsense variants in RPGRIP1L are expected to be pathogenic. This variant is interpreted as pathogenic. -

The p.Gln872X variant in RPGRIP1L has been reported in one French individual with Meckel Syndrome, who also carried a second variant (p.Q345X) in the same gene (Delous 2007 PMID: 17558509). This variant has also been reported in ClinVar (Variation ID 1074) and identified in 0.00004% (5/113470) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org). This nonsense variant leads to a premature termination codon at position 872, which is predicted to lead to a truncated or absent protein. Please note, the exon it resides in (exon 17) is alternatively spliced out of two of seven ubiquitously expressed transcripts. Complete loss of RPGRIP1L function is an established disease mechanism in RPGRIP1L-related disorders such as Joubert syndrome and Meckel syndrome (Delous 2007). Moreover, Rpgrip1l -/- mice show a similar phenotype to individuals affected with these disorders including polydactyly, craniofacial malformations, and left-right symmetry defects (Vierkotten 2007). In summary, although additional studies are required to fully establish its clinical significance, this variant meets criteria to be classified as likely pathogenic for autosomal recessive RPGRIP1L-related disorders.

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Gln872*) 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 (rs121918203, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with Meckel syndrome (PMID: 17558409). ClinVar contains an entry for this variant (Variation ID: 1074). For these reasons, this variant has been classified as Pathogenic. -
