The c.4616C>G (p.S1539C) alteration is located in exon 21 (coding exon 21) of the CTTNBP2 gene. This alteration results from a C to G substitution at nucleotide position 4616, causing the serine (S) at amino acid position 1539 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
