Genes affected

RCE1 (HGNC:13721): (Ras converting CAAX endopeptidase 1) This gene encodes an integral membrane protein which is classified as a member of the metalloproteinase family. This enzyme is thought to function in the maintenance and processing of CAAX-type prenylated proteins. [provided by RefSeq, Jul 2008]

The c.428C>T (p.A143V) alteration is located in exon 4 (coding exon 4) of the RCE1 gene. This alteration results from a C to T substitution at nucleotide position 428, causing the alanine (A) at amino acid position 143 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
