Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.3583G>A (p.G1195S) alteration is located in exon 4 (coding exon 3) of the KIAA1683 gene. This alteration results from a G to A substitution at nucleotide position 3583, causing the glycine (G) at amino acid position 1195 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
