The c.2243C>T (p.P748L) alteration is located in exon 19 (coding exon 19) of the LRRC7 gene. This alteration results from a C to T substitution at nucleotide position 2243, causing the proline (P) at amino acid position 748 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
