Genes affected

RALGAPA1 (HGNC:17770): (Ral GTPase activating protein catalytic subunit alpha 1) This gene encodes a major subunit of the RAL-GTPase activating protein. A similar protein in mouse binds E12, a transcriptional regulator of immunoglobulin genes. The mouse protein also functions in skeletal muscle by binding to the regulatory 14-3-3 proteins upon stimulation with insulin or muscle contraction. A pseudogene of this gene has been identified on chromosome 9. [provided by RefSeq, Oct 2016]

RALGAPA1 Gene-Disease associations (from GenCC):

• neurodevelopmental disorder with hypotonia, neonatal respiratory insufficiency, and thermodysregulation

  Inheritance: AR Classification: STRONG, MODERATE Submitted by: Ambry Genetics, G2P, Labcorp Genetics (formerly Invitae)
• complex neurodevelopmental disorder
