Genes affected
ERC1 (HGNC:17072): (ELKS/RAB6-interacting/CAST family member 1) The protein encoded by this gene is a member of a family of RIM-binding proteins. RIMs are active zone proteins that regulate neurotransmitter release. This gene has been found fused to the receptor-type tyrosine kinase gene RET by gene rearrangement due to the translocation t(10;12)(q11;p13) in thyroid papillary carcinoma. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.17G>A (p.R6H) alteration is located in exon 1 (coding exon 1) of the ERC1 gene. This alteration results from a G to A substitution at nucleotide position 17, causing the arginine (R) at amino acid position 6 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
