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).

Meckel-Gruber syndrome;C0431399:Familial aplasia of the vermis Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeJun 14, 2022This sequence change replaces threonine, which is neutral and polar, with isoleucine, which is neutral and non-polar, at codon 256 of the RPGRIP1L protein (p.Thr256Ile). This variant is present in population databases (rs151174849, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with RPGRIP1L-related conditions. ClinVar contains an entry for this variant (Variation ID: 461759). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
RPGRIP1L-related disorder Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingPreventionGenetics, part of Exact SciencesFeb 07, 2023The RPGRIP1L c.767C>T variant is predicted to result in the amino acid substitution p.Thr256Ile. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.011% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/16-53720354-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
