Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.903G>A (p.M301I) alteration is located in exon 8 (coding exon 8) of the APMAP gene. This alteration results from a G to A substitution at nucleotide position 903, causing the methionine (M) at amino acid position 301 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
