Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2024The c.1090G>A (p.G364S) alteration is located in exon 10 (coding exon 10) of the IFT57 gene. This alteration results from a G to A substitution at nucleotide position 1090, causing the glycine (G) at amino acid position 364 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
