Collection Method: clinical testing

The c.43C>T (p.R15W) alteration is located in exon 3 (coding exon 1) of the ATG101 gene. This alteration results from a C to T substitution at nucleotide position 43, causing the arginine (R) at amino acid position 15 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
