The c.287C>T (p.P96L) alteration is located in exon 2 (coding exon 2) of the LRRC73 gene. This alteration results from a C to T substitution at nucleotide position 287, causing the proline (P) at amino acid position 96 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
