Genes affected
MAGEC3 (HGNC:23798): (MAGE family member C3) This gene is a member of the MAGEC gene family. The members of this family are not expressed in normal tissues, except for testis, and are expressed in tumors of various histological types. The MAGEC genes are clustered on chromosome Xq26-q27. Two transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 04, 2024The c.667C>G (p.P223A) alteration is located in exon 4 (coding exon 4) of the MAGEC3 gene. This alteration results from a C to G substitution at nucleotide position 667, causing the proline (P) at amino acid position 223 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
