Genes affected
GNG7 (HGNC:4410): (G protein subunit gamma 7) Predicted to enable G-protein beta-subunit binding activity. Predicted to be involved in G protein-coupled receptor signaling pathway and regulation of adenylate cyclase activity. Predicted to act upstream of or within behavioral fear response; locomotory behavior; and receptor guanylyl cyclase signaling pathway. Located in extracellular exosome.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 16, 2022The c.55A>G (p.I19V) alteration is located in exon 3 (coding exon 1) of the GNG7 gene. This alteration results from a A to G substitution at nucleotide position 55, causing the isoleucine (I) at amino acid position 19 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
