Ambry Genetics

Jun 06, 2023

The c.2089C>G (p.R697G) alteration is located in exon 14 (coding exon 14) of the MCTP1 gene. This alteration results from a C to G substitution at nucleotide position 2089, causing the arginine (R) at amino acid position 697 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
