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 significance, criteria provided, single submitterclinical testingGeneDxAug 08, 2018A variant of uncertain significance has been identified in the PRICKLE1 gene. The S739F variant in the PRICKLE1 gene was previously identified in a patient with myelomeningocele and was not detected in controls so it was suggested to contribute to an increased risk for open neural tube defects; however, the variant was inherited from the patient's unaffected mother and did not co-segregate with neural tube defects in the extended family (Bosoi et al., 2011). The S739F variant is observed in 181/126496 (0.14%) alleles from individuals of European background in large population cohorts (Lek et al., 2016). In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. However, the S739F 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. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant. -

Uncertain significance, criteria provided, single submitterclinical testingInvitaeSep 07, 2022This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 739 of the PRICKLE1 protein (p.Ser739Phe). This variant is present in population databases (rs138452760, gnomAD 0.1%), and has an allele count higher than expected for a pathogenic variant. This missense change has been observed in individual(s) with myelomeningocele (PMID: 21901791). ClinVar contains an entry for this variant (Variation ID: 198918). 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. -

Likely benign, criteria provided, single submitterclinical testingAmbry GeneticsMay 25, 2021This 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. -
