Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.530C>T (p.P177L) alteration is located in exon 2 (coding exon 2) of the MYCT1 gene. This alteration results from a C to T substitution at nucleotide position 530, causing the proline (P) at amino acid position 177 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
