The c.488A>C (p.Q163P) alteration is located in exon 6 (coding exon 4) of the LYSMD4 gene. This alteration results from a A to C substitution at nucleotide position 488, causing the glutamine (Q) at amino acid position 163 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
