Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2023The c.1982G>A (p.C661Y) alteration is located in exon 9 (coding exon 9) of the CCDC142 gene. This alteration results from a G to A substitution at nucleotide position 1982, causing the cysteine (C) at amino acid position 661 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
