Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2023The c.278C>T (p.A93V) alteration is located in exon 3 (coding exon 3) of the EQTN gene. This alteration results from a C to T substitution at nucleotide position 278, causing the alanine (A) at amino acid position 93 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
