The c.269C>T (p.T90M) alteration is located in exon 4 (coding exon 2) of the CERS4 gene. This alteration results from a C to T substitution at nucleotide position 269, causing the threonine (T) at amino acid position 90 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
