Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2023The c.254G>A (p.R85Q) alteration is located in exon 3 (coding exon 2) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 254, causing the arginine (R) at amino acid position 85 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
