Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 22, 2023 | The c.611A>G (p.Y204C) alteration is located in exon 5 (coding exon 4) of the TTC33 gene. This alteration results from a A to G substitution at nucleotide position 611, causing the tyrosine (Y) at amino acid position 204 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
