Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.632T>A (p.I211N) alteration is located in exon 6 (coding exon 6) of the KIAA0907 gene. This alteration results from a T to A substitution at nucleotide position 632, causing the isoleucine (I) at amino acid position 211 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
