Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.2273G>A (p.R758Q) alteration is located in exon 17 (coding exon 17) of the MYO1G gene. This alteration results from a G to A substitution at nucleotide position 2273, causing the arginine (R) at amino acid position 758 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
