not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2023The c.20T>A (p.M7K) alteration is located in exon 1 (coding exon 1) of the MED31 gene. This alteration results from a T to A substitution at nucleotide position 20, causing the methionine (M) at amino acid position 7 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
