Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.208T>A (p.F70I) alteration is located in exon 3 (coding exon 3) of the EQTN gene. This alteration results from a T to A substitution at nucleotide position 208, causing the phenylalanine (F) at amino acid position 70 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
