Ambry Genetics

Jul 25, 2023

The c.12G>C (p.E4D) alteration is located in exon 1 (coding exon 1) of the SNRNP48 gene. This alteration results from a G to C substitution at nucleotide position 12, causing the glutamic acid (E) at amino acid position 4 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
