Significance: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.85C>T (p.R29C) alteration is located in exon 1 (coding exon 1) of the ECHDC3 gene. This alteration results from a C to T substitution at nucleotide position 85, causing the arginine (R) at amino acid position 29 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
