Ambry Genetics

Feb 13, 2024

The c.425G>A (p.R142Q) alteration is located in exon 5 (coding exon 4) of the HEXDC gene. This alteration results from a G to A substitution at nucleotide position 425, causing the arginine (R) at amino acid position 142 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
