The c.740C>T (p.P247L) alteration is located in exon 7 (coding exon 5) of the FAM114A1 gene. This alteration results from a C to T substitution at nucleotide position 740, causing the proline (P) at amino acid position 247 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
