Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 17, 2023The c.4220A>G (p.K1407R) alteration is located in exon 4 (coding exon 4) of the NACAD gene. This alteration results from a A to G substitution at nucleotide position 4220, causing the lysine (K) at amino acid position 1407 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
