Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 28, 2022The c.279C>A (p.F93L) alteration is located in exon 4 (coding exon 3) of the CFAP99 gene. This alteration results from a C to A substitution at nucleotide position 279, causing the phenylalanine (F) at amino acid position 93 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
