Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2022The c.2266G>A (p.V756I) alteration is located in exon 9 (coding exon 9) of the TTLL11 gene. This alteration results from a G to A substitution at nucleotide position 2266, causing the valine (V) at amino acid position 756 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
