Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 09, 2021The c.4348A>G (p.M1450V) alteration is located in exon 28 (coding exon 27) of the CFAP44 gene. This alteration results from a A to G substitution at nucleotide position 4348, causing the methionine (M) at amino acid position 1450 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
