Genes affected
MYCBP2 (HGNC:23386): (MYC binding protein 2) This gene encodes an E3 ubiquitin-protein ligase and member of the PHR (Phr1/MYCBP2, highwire and RPM-1) family of proteins. The encoded protein plays a role in axon guidance and synapse formation in the developing nervous system. In mammalian cells, this protein regulates the cAMP and mTOR signaling pathways, and may additionally regulate autophagy. Reduced expression of this gene has been observed in acute lymphoblastic leukemia patients and a mutation in this gene has been identified in patients with a rare inherited vision defect.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.13670G>A (p.R4557H) alteration is located in exon 81 (coding exon 81) of the MYCBP2 gene. This alteration results from a G to A substitution at nucleotide position 13670, causing the arginine (R) at amino acid position 4557 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
