Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.1460C>A (p.A487D) alteration is located in exon 13 (coding exon 11) of the ACSM2B gene. This alteration results from a C to A substitution at nucleotide position 1460, causing the alanine (A) at amino acid position 487 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
