Ambry Genetics

Nov 15, 2024

The c.415A>T (p.I139F) alteration is located in exon 6 (coding exon 5) of the FRMD8 gene. This alteration results from a A to T substitution at nucleotide position 415, causing the isoleucine (I) at amino acid position 139 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
