Genes affected
GJA9 (HGNC:19155): (gap junction protein alpha 9) Connexins, such as GJA9, are involved in the formation of gap junctions, intercellular conduits that directly connect the cytoplasms of contacting cells. Each gap junction channel is formed by docking of 2 hemichannels, each of which contains 6 connexin subunits (Sohl et al., 2003 [PubMed 12881038]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.1010G>A (p.S337N) alteration is located in exon 2 (coding exon 1) of the GJA9 gene. This alteration results from a G to A substitution at nucleotide position 1010, causing the serine (S) at amino acid position 337 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
