Collection Method: clinical testing

The c.985G>A (p.G329S) alteration is located in exon 6 (coding exon 4) of the GHDC gene. This alteration results from a G to A substitution at nucleotide position 985, causing the glycine (G) at amino acid position 329 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
