Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.487G>A (p.G163S) alteration is located in exon 4 (coding exon 3) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 487, causing the glycine (G) at amino acid position 163 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
