Genes affected

MKRN2 (HGNC:7113): (makorin ring finger protein 2) This gene encodes a probable E3 ubiquitin ligase containing several zinc finger domains, that is a member of the makorin RING zinc-finger protein family. This gene overlaps the v-raf-1 murine leukemia viral oncogene homolog 1 (RAF1) gene in an antisense orientation and may have a co-regulatory function with RAF1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2012]

Ambry Genetics

Feb 15, 2023

The c.632C>T (p.A211V) alteration is located in exon 4 (coding exon 4) of the MKRN2 gene. This alteration results from a C to T substitution at nucleotide position 632, causing the alanine (A) at amino acid position 211 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
