Ambry Genetics

Jan 09, 2024

The c.188G>A (p.R63Q) alteration is located in exon 4 (coding exon 4) of the IQCJ gene. This alteration results from a G to A substitution at nucleotide position 188, causing the arginine (R) at amino acid position 63 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
