The c.589C>A (p.P197T) alteration is located in exon 7 (coding exon 7) of the SH3YL1 gene. This alteration results from a C to A substitution at nucleotide position 589, causing the proline (P) at amino acid position 197 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
