Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 29, 2023The c.220A>G (p.K74E) alteration is located in exon 3 (coding exon 2) of the TCP10L gene. This alteration results from a A to G substitution at nucleotide position 220, causing the lysine (K) at amino acid position 74 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
