Ambry Genetics

Apr 01, 2024

The c.2244G>T (p.L748F) alteration is located in exon 14 (coding exon 14) of the CCDC191 gene. This alteration results from a G to T substitution at nucleotide position 2244, causing the leucine (L) at amino acid position 748 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
