Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 24, 2024The c.802C>T (p.R268W) alteration is located in exon 2 (coding exon 1) of the CCDC71 gene. This alteration results from a C to T substitution at nucleotide position 802, causing the arginine (R) at amino acid position 268 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
