Ambry Genetics

Oct 01, 2024

The c.664C>A (p.L222M) alteration is located in exon 5 (coding exon 5) of the RELL2 gene. This alteration results from a C to A substitution at nucleotide position 664, causing the leucine (L) at amino acid position 222 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
