Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.1870C>T (p.L624F) alteration is located in exon 11 (coding exon 10) of the DQX1 gene. This alteration results from a C to T substitution at nucleotide position 1870, causing the leucine (L) at amino acid position 624 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
