The c.752A>T (p.E251V) alteration is located in exon 7 (coding exon 7) of the SNRNP48 gene. This alteration results from a A to T substitution at nucleotide position 752, causing the glutamic acid (E) at amino acid position 251 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
