Genes affected

RPH3A (HGNC:17056): (rabphilin 3A) The protein encoded by this gene is thought to be an effector for RAB3A, which is a small G protein that acts in the late stages of neurotransmitter exocytosis. The encoded protein may be involved in neurotransmitter release and synaptic vesicle traffic. [provided by RefSeq, Dec 2016]

RPH3A Gene-Disease associations (from GenCC):

• complex neurodevelopmental disorder

  Inheritance: AD Classification: MODERATE Submitted by: Ambry Genetics
• neurodevelopmental disorder

  Inheritance: AD Classification: LIMITED Submitted by: G2P
• congenital myasthenic syndrome

  Inheritance: AR Classification: LIMITED Submitted by: Ambry Genetics
