Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.413C>T (p.P138L) alteration is located in exon 6 (coding exon 6) of the PTCD3 gene. This alteration results from a C to T substitution at nucleotide position 413, causing the proline (P) at amino acid position 138 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
