The c.89C>T (p.P30L) alteration is located in exon 3 (coding exon 1) of the FLYWCH2 gene. This alteration results from a C to T substitution at nucleotide position 89, causing the proline (P) at amino acid position 30 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
