Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 08, 2022The c.983A>G (p.D328G) alteration is located in exon 1 (coding exon 1) of the KIAA1671 gene. This alteration results from a A to G substitution at nucleotide position 983, causing the aspartic acid (D) at amino acid position 328 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
