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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.1066G>A (p.E356K) alteration is located in exon 7 (coding exon 7) of the MKRN2 gene. This alteration results from a G to A substitution at nucleotide position 1066, causing the glutamic acid (E) at amino acid position 356 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
