Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2023The c.2057T>A (p.L686Q) alteration is located in exon 13 (coding exon 12) of the USHBP1 gene. This alteration results from a T to A substitution at nucleotide position 2057, causing the leucine (L) at amino acid position 686 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
