The c.89G>A (p.R30H) alteration is located in exon 4 (coding exon 2) of the CDIP1 gene. This alteration results from a G to A substitution at nucleotide position 89, causing the arginine (R) at amino acid position 30 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
