Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.1079G>A (p.R360Q) alteration is located in exon 9 (coding exon 9) of the APMAP gene. This alteration results from a G to A substitution at nucleotide position 1079, causing the arginine (R) at amino acid position 360 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
