The c.820C>T (p.H274Y) alteration is located in exon 6 (coding exon 6) of the CFAP77 gene. This alteration results from a C to T substitution at nucleotide position 820, causing the histidine (H) at amino acid position 274 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
