Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 27, 2024The c.1220C>T (p.T407M) alteration is located in exon 8 (coding exon 8) of the KLHL18 gene. This alteration results from a C to T substitution at nucleotide position 1220, causing the threonine (T) at amino acid position 407 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
