The c.485C>T (p.A162V) alteration is located in exon 7 (coding exon 5) of the CERS4 gene. This alteration results from a C to T substitution at nucleotide position 485, causing the alanine (A) at amino acid position 162 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
