Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 26, 2024The c.533G>A (p.R178H) alteration is located in exon 4 (coding exon 4) of the CFAP77 gene. This alteration results from a G to A substitution at nucleotide position 533, causing the arginine (R) at amino acid position 178 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
