Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2023The c.251C>A (p.T84N) alteration is located in exon 1 (coding exon 1) of the AIM1 gene. This alteration results from a C to A substitution at nucleotide position 251, causing the threonine (T) at amino acid position 84 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
