not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2023The c.604G>A (p.A202T) alteration is located in exon 1 (coding exon 1) of the AIM1 gene. This alteration results from a G to A substitution at nucleotide position 604, causing the alanine (A) at amino acid position 202 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
