Ambry Genetics

Feb 16, 2023

The c.416C>A (p.S139Y) alteration is located in exon 5 (coding exon 5) of the SNRNP48 gene. This alteration results from a C to A substitution at nucleotide position 416, causing the serine (S) at amino acid position 139 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
