The c.3577T>C (p.S1193P) alteration is located in exon 23 (coding exon 19) of the ATP10B gene. This alteration results from a T to C substitution at nucleotide position 3577, causing the serine (S) at amino acid position 1193 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
