Collection Method:clinical testing

The c.2081C>T (p.S694L) alteration is located in exon 16 (coding exon 15) of the MEGF11 gene. This alteration results from a C to T substitution at nucleotide position 2081, causing the serine (S) at amino acid position 694 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
