The c.1216T>C (p.Y406H) alteration is located in exon 13 (coding exon 13) of the RANBP3L gene. This alteration results from a T to C substitution at nucleotide position 1216, causing the tyrosine (Y) at amino acid position 406 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
