The c.331G>T (p.V111F) alteration is located in exon 3 (coding exon 3) of the CDHR3 gene. This alteration results from a G to T substitution at nucleotide position 331, causing the valine (V) at amino acid position 111 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
