The c.88C>G (p.R30G) alteration is located in exon 1 (coding exon 1) of the ANKRD33 gene. This alteration results from a C to G substitution at nucleotide position 88, causing the arginine (R) at amino acid position 30 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
