Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 06, 2022The c.715A>T (p.M239L) alteration is located in exon 6 (coding exon 6) of the KIF3A gene. This alteration results from a A to T substitution at nucleotide position 715, causing the methionine (M) at amino acid position 239 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
