Submissions by phenotype
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jul 09, 2021 | The c.6452G>A (p.R2151Q) alteration is located in exon 45 (coding exon 45) of the CACNA1A gene. This alteration results from a G to A substitution at nucleotide position 6452, causing the arginine (R) at amino acid position 2151 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
