Genes affected

PRICKLE4 (HGNC:16805): (prickle planar cell polarity protein 4) C6ORF49 is a member of the LIM domain protein family (Teufel et al., 2005 [PubMed 15702247]).[supplied by OMIM, Mar 2008]

FRS3 (HGNC:16970): (fibroblast growth factor receptor substrate 3) This gene encodes a substrate for the fibroblast growth factor receptor. The encoded protein is found in the peripheral plasma membrane and links fibroblast growth factor receptor stimulation to activators of Ras. The encoded protein down-regulates extracellular regulated kinase 2 through direct binding. [provided by RefSeq, Jul 2013]

Collection Method: clinical testing

The c.50C>T (p.P17L) alteration is located in exon 3 (coding exon 1) of the PRICKLE4 gene. This alteration results from a C to T substitution at nucleotide position 50, causing the proline (P) at amino acid position 17 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
