Genes affected

GORAB (HGNC:25676): (golgin, RAB6 interacting) This gene encodes a member of the golgin family, a group of coiled-coil proteins localized to the Golgi. The encoded protein may function in the secretory pathway. The encoded protein, which also localizes to the cytoplasm, was identified by interactions with the N-terminal kinase-like protein, and thus it may function in mitosis. Mutations in this gene have been associated with geroderma osteodysplastica. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

The c.5G>T (p.S2I) alteration is located in exon 1 (coding exon 1) of the GORAB gene. This alteration results from a G to T substitution at nucleotide position 5, causing the serine (S) at amino acid position 2 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

This sequence change replaces serine with isoleucine at codon 2 of the GORAB protein (p.Ser2Ile). The serine residue is weakly conserved and there is a large physicochemical difference between serine and isoleucine. This variant is present in population databases (rs148313748, ExAC 0.005%). This variant has not been reported in the literature in individuals affected with GORAB-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
