Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2022The c.133A>T (p.M45L) alteration is located in exon 1 (coding exon 1) of the CFAP77 gene. This alteration results from a A to T substitution at nucleotide position 133, causing the methionine (M) at amino acid position 45 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
