Genes affected
PRICKLE1 (HGNC:17019): (prickle planar cell polarity protein 1) This gene encodes a nuclear receptor that may be a negative regulator of the Wnt/beta-catenin signaling pathway. The encoded protein localizes to the nuclear membrane and has been implicated in the nuclear trafficking of the transcription repressors REST/NRSF and REST4. Mutations in this gene have been linked to progressive myoclonus epilepsy. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 3.

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.1435G>A (p.G479R) alteration is located in exon 7 (coding exon 6) of the PRICKLE1 gene. This alteration results from a G to A substitution at nucleotide position 1435, causing the glycine (G) at amino acid position 479 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

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. 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 disruptive. ClinVar contains an entry for this variant (Variation ID: 198621). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. This variant is present in population databases (rs570770626, gnomAD 0.06%). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 479 of the PRICKLE1 protein (p.Gly479Arg). -
