not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 17, 2024The c.244C>T (p.R82W) alteration is located in exon 3 (coding exon 3) of the TMED8 gene. This alteration results from a C to T substitution at nucleotide position 244, causing the arginine (R) at amino acid position 82 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
