Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2023The c.698A>G (p.K233R) alteration is located in exon 7 (coding exon 6) of the CFAP99 gene. This alteration results from a A to G substitution at nucleotide position 698, causing the lysine (K) at amino acid position 233 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
