Published previously in the presence of a second GJA1 variant, in association with hypoplastic left heart syndrome in several unrelated individuals (Dasgupta et al., 2001); In vitro functional study showed that the R362Q variant abolishes phosphorylation of the connexin 43 channel regulation domain (Dasgupta et al., 2001); In silico analysis supports that this missense variant does not alter protein structure/function; This variant is associated with the following publications: (PMID: 22995991, 31564432, 22090377, 11470490, 31019026)
