The c.670T>C (p.Y224H) alteration is located in exon 7 (coding exon 7) of the DBNL gene. This alteration results from a T to C substitution at nucleotide position 670, causing the tyrosine (Y) at amino acid position 224 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
