Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2021The c.2156A>G (p.N719S) alteration is located in exon 13 (coding exon 12) of the AKNAD1 gene. This alteration results from a A to G substitution at nucleotide position 2156, causing the asparagine (N) at amino acid position 719 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
