not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.2368C>T (p.R790C) alteration is located in exon 22 (coding exon 21) of the EXD3 gene. This alteration results from a C to T substitution at nucleotide position 2368, causing the arginine (R) at amino acid position 790 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
