The c.3731C>A (p.S1244Y) alteration is located in exon 23 (coding exon 23) of the CNTNAP3B gene. This alteration results from a C to A substitution at nucleotide position 3731, causing the serine (S) at amino acid position 1244 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
