Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 27, 2023The c.572G>A (p.R191Q) alteration is located in exon 5 (coding exon 5) of the MYO1H gene. This alteration results from a G to A substitution at nucleotide position 572, causing the arginine (R) at amino acid position 191 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
