Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 28, 2024The c.1088G>A (p.R363Q) alteration is located in exon 3 (coding exon 2) of the KDF1 gene. This alteration results from a G to A substitution at nucleotide position 1088, causing the arginine (R) at amino acid position 363 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
