Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2024The c.473C>T (p.P158L) alteration is located in exon 7 (coding exon 7) of the MAST3 gene. This alteration results from a C to T substitution at nucleotide position 473, causing the proline (P) at amino acid position 158 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
