Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 04, 2023The c.620A>C (p.Q207P) alteration is located in exon 5 (coding exon 5) of the MYO1H gene. This alteration results from a A to C substitution at nucleotide position 620, causing the glutamine (Q) at amino acid position 207 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
