Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.80C>T (p.T27M) 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 80, causing the threonine (T) at amino acid position 27 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
