Ambry Genetics

Nov 20, 2024

The c.2231C>T (p.S744L) alteration is located in exon 3 (coding exon 1) of the ELFN2 gene. This alteration results from a C to T substitution at nucleotide position 2231, causing the serine (S) at amino acid position 744 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
