Collection Method: clinical testing

The c.1288C>T (p.R430C) alteration is located in exon 14 (coding exon 14) of the RANBP3L gene. This alteration results from a C to T substitution at nucleotide position 1288, causing the arginine (R) at amino acid position 430 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
