The c.11695C>A (p.P3899T) alteration is located in exon 63 (coding exon 63) of the DNAH7 gene. This alteration results from a C to A substitution at nucleotide position 11695, causing the proline (P) at amino acid position 3899 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
