Ambry Genetics

Apr 23, 2024

The c.219C>G (p.H73Q) alteration is located in exon 3 (coding exon 3) of the GRTP1 gene. This alteration results from a C to G substitution at nucleotide position 219, causing the histidine (H) at amino acid position 73 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
