Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 28, 2021 | The c.919G>A (p.G307R) alteration is located in exon 5 (coding exon 5) of the AQP4 gene. This alteration results from a G to A substitution at nucleotide position 919, causing the glycine (G) at amino acid position 307 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
