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.

This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 794 of the PRICKLE1 protein (p.Tyr794His). This variant is present in population databases (rs201705679, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 570567). 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. 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. -
