The c.427C>T (p.L143F) alteration is located in exon 4 (coding exon 4) of the CERS6 gene. This alteration results from a C to T substitution at nucleotide position 427, causing the leucine (L) at amino acid position 143 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
