not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2023The c.855C>A (p.H285Q) alteration is located in exon 6 (coding exon 6) of the TMED8 gene. This alteration results from a C to A substitution at nucleotide position 855, causing the histidine (H) at amino acid position 285 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
