Ambry Genetics

Nov 08, 2022

The c.66C>A (p.F22L) alteration is located in exon 3 (coding exon 1) of the MOBP gene. This alteration results from a C to A substitution at nucleotide position 66, causing the phenylalanine (F) at amino acid position 22 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
