Genes affected
CACNG4 (HGNC:1408): (calcium voltage-gated channel auxiliary subunit gamma 4) The protein encoded by this gene is a type I transmembrane AMPA receptor regulatory protein (TARP). TARPs regulate both trafficking and channel gating of the AMPA receptors. This gene is part of a functionally diverse eight-member protein subfamily of the PMP-22/EMP/MP20 family and is located in a cluster with two family members, a type II TARP and a calcium channel gamma subunit.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2021The c.713A>G (p.Y238C) alteration is located in exon 4 (coding exon 4) of the CACNG4 gene. This alteration results from a A to G substitution at nucleotide position 713, causing the tyrosine (Y) at amino acid position 238 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
