Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.1508G>A (p.G503E) alteration is located in exon 12 (coding exon 12) of the KIAA0907 gene. This alteration results from a G to A substitution at nucleotide position 1508, causing the glycine (G) at amino acid position 503 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
