The c.431G>A (p.G144D) alteration is located in exon 5 (coding exon 4) of the CBARP gene. This alteration results from a G to A substitution at nucleotide position 431, causing the glycine (G) at amino acid position 144 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
