The c.8554G>T (p.V2852L) alteration is located in exon 54 (coding exon 53) of the DNAH12 gene. This alteration results from a G to T substitution at nucleotide position 8554, causing the valine (V) at amino acid position 2852 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
