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.

The p.P38L variant (also known as c.113C>T), located in coding exon 1 of the PRICKLE1 gene, results from a C to T substitution at nucleotide position 113. The proline at codon 38 is replaced by leucine, an amino acid with similar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The P38L variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The P38L variant is observed in 77/18,870 (0.4%) alleles from individuals of East Asian background (Lek et al., 2016). The P38L variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -
