The c.1027C>T (p.L343F) alteration is located in exon 5 (coding exon 4) of the FAM53A gene. This alteration results from a C to T substitution at nucleotide position 1027, causing the leucine (L) at amino acid position 343 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
