Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 25, 2022The c.506G>A (p.R169Q) alteration is located in exon 2 (coding exon 2) of the GNA12 gene. This alteration results from a G to A substitution at nucleotide position 506, causing the arginine (R) at amino acid position 169 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
