Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2024The c.937C>T (p.R313C) alteration is located in exon 6 (coding exon 6) of the TMED8 gene. This alteration results from a C to T substitution at nucleotide position 937, causing the arginine (R) at amino acid position 313 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
