Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 16, 2022The c.119G>T (p.R40L) alteration is located in exon 3 (coding exon 2) of the KIAA1644 gene. This alteration results from a G to T substitution at nucleotide position 119, causing the arginine (R) at amino acid position 40 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
