Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.361A>G (p.I121V) alteration is located in exon 4 (coding exon 3) of the MPG gene. This alteration results from a A to G substitution at nucleotide position 361, causing the isoleucine (I) at amino acid position 121 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
