The c.1181C>T (p.P394L) alteration is located in exon 11 (coding exon 8) of the NCOA7 gene. This alteration results from a C to T substitution at nucleotide position 1181, causing the proline (P) at amino acid position 394 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
