Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 27, 2023The c.908C>T (p.P303L) alteration is located in exon 3 (coding exon 1) of the MAGEC2 gene. This alteration results from a C to T substitution at nucleotide position 908, causing the proline (P) at amino acid position 303 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
