Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 01, 2023The c.2368G>A (p.A790T) 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 2368, causing the alanine (A) at amino acid position 790 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
