The c.2299C>T (p.L767F) alteration is located in exon 19 (coding exon 19) of the CCDC175 gene. This alteration results from a C to T substitution at nucleotide position 2299, causing the leucine (L) at amino acid position 767 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
