Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.94A>G (p.M32V) alteration is located in exon 3 (coding exon 2) of the KRBOX1 gene. This alteration results from a A to G substitution at nucleotide position 94, causing the methionine (M) at amino acid position 32 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
