The c.1891G>A (p.E631K) alteration is located in exon 12 (coding exon 11) of the USHBP1 gene. This alteration results from a G to A substitution at nucleotide position 1891, causing the glutamic acid (E) at amino acid position 631 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
