The c.2573T>C (p.L858S) alteration is located in exon 24 (coding exon 23) of the CC2D1B gene. This alteration results from a T to C substitution at nucleotide position 2573, causing the leucine (L) at amino acid position 858 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
