Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2022The c.2818G>A (p.V940M) alteration is located in exon 21 (coding exon 21) of the MYO1G gene. This alteration results from a G to A substitution at nucleotide position 2818, causing the valine (V) at amino acid position 940 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
