Genes affected

MYT1 (HGNC:7622): (myelin transcription factor 1) The protein encoded by this gene is a member of a family of neural specific, zinc finger-containing DNA-binding proteins. The protein binds to the promoter regions of proteolipid proteins of the central nervous system and plays a role in the developing nervous system. [provided by RefSeq, Jul 2008]

MYT1 Gene-Disease associations (from GenCC):

• craniofacial microsomia

  Inheritance: AD Classification: LIMITED Submitted by: G2P

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.382 is higher than 0.05.
