Jan 10, 2023

The c.221G>A (p.R74H) alteration is located in exon 3 (coding exon 3) of the CLPTM1 gene. This alteration results from a G to A substitution at nucleotide position 221, causing the arginine (R) at amino acid position 74 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
