Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 21, 2024The c.815G>A (p.R272H) alteration is located in exon 6 (coding exon 6) of the TMED8 gene. This alteration results from a G to A substitution at nucleotide position 815, causing the arginine (R) at amino acid position 272 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
