Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.817C>T (p.R273W) alteration is located in exon 6 (coding exon 5) of the RMDN3 gene. This alteration results from a C to T substitution at nucleotide position 817, causing the arginine (R) at amino acid position 273 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
