The c.1145C>T (p.P382L) alteration is located in exon 9 (coding exon 9) of the SRRM1 gene. This alteration results from a C to T substitution at nucleotide position 1145, causing the proline (P) at amino acid position 382 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
