The c.1156C>T (p.L386F) alteration is located in exon 8 (coding exon 8) of the CNPPD1 gene. This alteration results from a C to T substitution at nucleotide position 1156, causing the leucine (L) at amino acid position 386 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
