Jun 17, 2022

The c.277T>C (p.F93L) alteration is located in exon 2 (coding exon 2) of the CD300C gene. This alteration results from a T to C substitution at nucleotide position 277, causing the phenylalanine (F) at amino acid position 93 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
