Genes affected
RIN2 (HGNC:18750): (Ras and Rab interactor 2) The RAB5 protein is a small GTPase involved in membrane trafficking in the early endocytic pathway. The protein encoded by this gene binds the GTP-bound form of the RAB5 protein preferentially over the GDP-bound form, and functions as a guanine nucleotide exchange factor for RAB5. The encoded protein is found primarily as a tetramer in the cytoplasm and does not bind other members of the RAB family. Mutations in this gene cause macrocephaly alopecia cutis laxa and scoliosis (MACS) syndrome, an elastic tissue disorder, as well as the related connective tissue disorder, RIN2 syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jun 2011]

Submissions by phenotype

not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 28, 2022The RIN2 gene has multiple clinically relevant transcripts. This variant occurs in alternate transcript NM_001242581.1, and corresponds to NM_018993.3:c.-2922C>G in the primary transcript. 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. This variant has not been reported in the literature in individuals affected with RIN2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.002%). This sequence change results in a premature translational stop signal in the RIN2 gene (p.Ser4*). However, it is currently unclear if variants that occur in this region of the gene cause disease. -
