Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2022The c.68G>T (p.R23L) alteration is located in exon 1 (coding exon 1) of the CFAP77 gene. This alteration results from a G to T substitution at nucleotide position 68, causing the arginine (R) at amino acid position 23 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
