not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2022The c.853G>A (p.V285I) alteration is located in exon 5 (coding exon 4) of the MPG gene. This alteration results from a G to A substitution at nucleotide position 853, causing the valine (V) at amino acid position 285 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
