The c.836C>A (p.A279E) alteration is located in exon 3 (coding exon 2) of the CTU1 gene. This alteration results from a C to A substitution at nucleotide position 836, causing the alanine (A) at amino acid position 279 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
