Genes affected
ERC2 (HGNC:31922): (ELKS/RAB6-interacting/CAST family member 2) This gene encodes a protein that belongs to the Rab3-interacting molecule (RIM)-binding protein family. Members of this protein family form part of the cytomatrix at the active zone (CAZ) complex and function as regulators of neurotransmitter release. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2015]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2024The c.1832G>A (p.R611K) alteration is located in exon 9 (coding exon 8) of the ERC2 gene. This alteration results from a G to A substitution at nucleotide position 1832, causing the arginine (R) at amino acid position 611 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
