The c.637C>G (p.L213V) alteration is located in exon 7 (coding exon 7) of the CERS6 gene. This alteration results from a C to G substitution at nucleotide position 637, causing the leucine (L) at amino acid position 213 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
