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.

Uncertain:2

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Feb 02, 2018	A variant of uncertain significance has been identified in the PRICKLE1 gene. The P802S variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The P802S variant is observed in 45/10,406 (0.4%) alleles from individuals of African background (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The P802S variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. However, this substitution occurs at a position that is not conserved, and Serine is observed at this position in another species. Additionally, in silico analysis predicts this variant likely does not alter the protein structure/function. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -

Likely benign, criteria provided, single submitter	clinical testing	Ambry Genetics	Apr 26, 2018	This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
