Genes affected

GJC3 (HGNC:17495): (gap junction protein gamma 3) This gene encodes a gap junction protein. The encoded protein, also known as a connexin, plays a role in formation of gap junctions, which provide direct connections between neighboring cells. Mutations in this gene have been reported to be associated with nonsyndromic hearing loss.[provided by RefSeq, Feb 2010]

Sep 01, 2021

The c.169C>G (p.Q57E) alteration is located in exon 1 (coding exon 1) of the GJC3 gene. This alteration results from a C to G substitution at nucleotide position 169, causing the glutamine (Q) at amino acid position 57 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
