Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.1109G>A (p.S370N) 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 1109, causing the serine (S) at amino acid position 370 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
