The c.490G>C (p.A164P) alteration is located in exon 6 (coding exon 6) of the HMGCLL1 gene. This alteration results from a G to C substitution at nucleotide position 490, causing the alanine (A) at amino acid position 164 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
