Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.727G>C (p.D243H) alteration is located in exon 7 (coding exon 7) of the APMAP gene. This alteration results from a G to C substitution at nucleotide position 727, causing the aspartic acid (D) at amino acid position 243 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
