The c.1454C>A (p.A485E) alteration is located in exon 5 (coding exon 4) of the LRRC24 gene. This alteration results from a C to A substitution at nucleotide position 1454, causing the alanine (A) at amino acid position 485 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
