Genes affected

MAGEA12 (HGNC:6799): (MAGE family member A12) This gene is closely related to several other genes clustered on chromosome X. These genes may be overexpressed in tumors. Multiple alternatively spliced variants encoding the same protein have been identified. [provided by RefSeq, Jun 2014]

CSAG4 (HGNC:):

CSAG4 (HGNC:20923): (CSAG family member 4 (pseudogene))

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
