not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2024The c.847C>T (p.R283C) alteration is located in exon 9 (coding exon 9) of the EXD1 gene. This alteration results from a C to T substitution at nucleotide position 847, causing the arginine (R) at amino acid position 283 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
