not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.659C>T (p.P220L) 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 659, causing the proline (P) at amino acid position 220 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
