The NM_006150.5(PRICKLE3):​c.1103T>C​(p.Leu368Pro) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Genomes: not found (cov: 23)
• Consequence: PRICKLE3 NM_006150.5 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 4.94

Genes affected

PRICKLE3 (HGNC:6645): (prickle planar cell polarity protein 3) LIM domain only 6 is a three LIM domain-containing protein. The LIM domain is a cysteine-rich sequence motif that binds zinc atoms to form a specific protein-binding interface for protein-protein interactions. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.32737368).

The c.1103T>C (p.L368P) alteration is located in exon 8 (coding exon 8) of the PRICKLE3 gene. This alteration results from a T to C substitution at nucleotide position 1103, causing the leucine (L) at amino acid position 368 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
