Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2023The c.5327C>T (p.A1776V) alteration is located in exon 14 (coding exon 13) of the ZNFX1 gene. This alteration results from a C to T substitution at nucleotide position 5327, causing the alanine (A) at amino acid position 1776 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
