Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 01, 2023The c.685G>A (p.A229T) alteration is located in exon 7 (coding exon 7) of the KIAA0930 gene. This alteration results from a G to A substitution at nucleotide position 685, causing the alanine (A) at amino acid position 229 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
