Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.3661G>A (p.V1221M) alteration is located in exon 2 (coding exon 2) of the NACAD gene. This alteration results from a G to A substitution at nucleotide position 3661, causing the valine (V) at amino acid position 1221 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
