Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.574C>T (p.R192C) alteration is located in exon 4 (coding exon 4) of the CFAP77 gene. This alteration results from a C to T substitution at nucleotide position 574, causing the arginine (R) at amino acid position 192 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
