Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2024The c.104G>A (p.R35H) alteration is located in exon 1 (coding exon 1) of the MYO1H gene. This alteration results from a G to A substitution at nucleotide position 104, causing the arginine (R) at amino acid position 35 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
