The c.1257G>C (p.Q419H) alteration is located in exon 3 (coding exon 3) of the BTBD17 gene. This alteration results from a G to C substitution at nucleotide position 1257, causing the glutamine (Q) at amino acid position 419 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
