Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.365T>C (p.I122T) alteration is located in exon 5 (coding exon 4) of the RFESD gene. This alteration results from a T to C substitution at nucleotide position 365, causing the isoleucine (I) at amino acid position 122 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
