Mendeliome v1.1884 MYZAP Zornitza Stark changed review comment from: 10 individuals from four unrelated families with bi-allelic variants in this gene with DCM. Supportive zebrafish model. Note the MYZAP and GCOM1 genes are part of the GRINL1A complex transcription unit. Some of the reported variants affect GCOM1 with postulated effect on MYZAP due to read through transcription (two families), and in the rest of the families MYZAP was affected directly.

The MYZAP gene is part of the GRINL1A complex transcription unit (CTU), or GCOM1, which also includes the downstream POLR2M gene, or GRINL1A.. Some of the reported variants affect GCOM1 with postulated effect on MYZAP due to read through transcription (two families), and in the rest of the families MYZAP was affected directly.

Transcription from an upstream promoter within the GRINL1A CTU produces 2 types of alternatively spliced transcripts: MYZAP transcripts, also called GRINL1A upstream (GUP) transcripts, which include only exons from the MYZAP gene, and GRINL1A combined (GCOM) transcripts, which include exons from both the MYZAP gene and the downstream POLR2M gene. Transcription of the POLR2M gene initiates at a downstream promoter within the GRINL1A CTU and produces alternatively spliced POLR2M transcripts, also called GRINL1A downstream (GDOWN) transcripts, which include only exons from the POLR2M gene
