Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 17, 2022The c.643G>T (p.D215Y) alteration is located in exon 6 (coding exon 6) of the CCDC91 gene. This alteration results from a G to T substitution at nucleotide position 643, causing the aspartic acid (D) at amino acid position 215 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
