not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 25, 2024The c.262G>T (p.A88S) alteration is located in exon 3 (coding exon 3) of the KLHL18 gene. This alteration results from a G to T substitution at nucleotide position 262, causing the alanine (A) at amino acid position 88 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
