The c.10520T>C (p.F3507S) alteration is located in exon 67 (coding exon 67) of the CSMD3 gene. This alteration results from a T to C substitution at nucleotide position 10520, causing the phenylalanine (F) at amino acid position 3507 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
