Collection Method: clinical testing

The c.1102T>C (p.F368L) alteration is located in exon 6 (coding exon 6) of the BEGAIN gene. This alteration results from a T to C substitution at nucleotide position 1102, causing the phenylalanine (F) at amino acid position 368 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
