Ambry Genetics

May 23, 2023

The c.623C>T (p.P208L) alteration is located in exon 5 (coding exon 4) of the MIDN gene. This alteration results from a C to T substitution at nucleotide position 623, causing the proline (P) at amino acid position 208 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
