Genes affected
MAGEC2 (HGNC:13574): (MAGE family member C2) This gene is a member of the MAGEC gene family. It is not expressed in normal tissues, except for testis, and is expressed in tumors of various histological types. This gene and the other MAGEC genes are clustered on chromosome Xq26-q27.

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 13, 2021The c.19G>A (p.V7I) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a G to A substitution at nucleotide position 19, causing the valine (V) at amino acid position 7 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
