Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 15, 2024The c.514G>A (p.G172S) alteration is located in exon 5 (coding exon 5) of the CCDC91 gene. This alteration results from a G to A substitution at nucleotide position 514, causing the glycine (G) at amino acid position 172 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
