Genes affected
GJD4 (HGNC:23296): (gap junction protein delta 4) Connexins, such as GJD4, 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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 12, 2024 | The c.448C>T (p.R150W) alteration is located in exon 2 (coding exon 2) of the GJD4 gene. This alteration results from a C to T substitution at nucleotide position 448, causing the arginine (R) at amino acid position 150 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
