Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2024The c.580G>A (p.G194S) alteration is located in exon 7 (coding exon 4) of the GTDC1 gene. This alteration results from a G to A substitution at nucleotide position 580, causing the glycine (G) at amino acid position 194 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
