Collection Method: clinical testing

The c.164G>A (p.R55Q) alteration is located in exon 4 (coding exon 2) of the ZMAT5 gene. This alteration results from a G to A substitution at nucleotide position 164, causing the arginine (R) at amino acid position 55 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
