Ambry Genetics

Jun 11, 2021

The c.253C>T (p.L85F) alteration is located in exon 3 (coding exon 1) of the MFSD6 gene. This alteration results from a C to T substitution at nucleotide position 253, causing the leucine (L) at amino acid position 85 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
