Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2022The c.187G>A (p.V63M) alteration is located in exon 2 (coding exon 2) of the MYO1H gene. This alteration results from a G to A substitution at nucleotide position 187, causing the valine (V) at amino acid position 63 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
