The c.1127T>C (p.F376S) alteration is located in exon 5 (coding exon 5) of the AADACL2 gene. This alteration results from a T to C substitution at nucleotide position 1127, causing the phenylalanine (F) at amino acid position 376 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
