Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 23, 2021The c.91G>A (p.V31M) alteration is located in exon 1 (coding exon 1) of the LEXM gene. This alteration results from a G to A substitution at nucleotide position 91, causing the valine (V) at amino acid position 31 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
