The c.527G>A (p.R176H) alteration is located in exon 5 (coding exon 5) of the SNRNP48 gene. This alteration results from a G to A substitution at nucleotide position 527, causing the arginine (R) at amino acid position 176 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
