Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 22, 2023The c.512T>C (p.I171T) alteration is located in exon 3 (coding exon 3) of the ZNF688 gene. This alteration results from a T to C substitution at nucleotide position 512, causing the isoleucine (I) at amino acid position 171 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
