Collection Method: clinical testing

The c.1798C>T (p.P600S) alteration is located in exon 11 (coding exon 9) of the ATG9A gene. This alteration results from a C to T substitution at nucleotide position 1798, causing the proline (P) at amino acid position 600 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
