The c.1885T>A (p.L629I) alteration is located in exon 17 (coding exon 16) of the CCDC178 gene. This alteration results from a T to A substitution at nucleotide position 1885, causing the leucine (L) at amino acid position 629 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
