Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 28, 2023The c.175G>A (p.E59K) alteration is located in exon 3 (coding exon 2) of the CCDC171 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the glutamic acid (E) at amino acid position 59 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
