Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 26, 2024The c.121G>A (p.E41K) alteration is located in exon 2 (coding exon 2) of the EQTN gene. This alteration results from a G to A substitution at nucleotide position 121, causing the glutamic acid (E) at amino acid position 41 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
