Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 20, 2022The c.382C>A (p.L128M) alteration is located in exon 4 (coding exon 3) of the MPG gene. This alteration results from a C to A substitution at nucleotide position 382, causing the leucine (L) at amino acid position 128 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
