The c.4441G>C (p.D1481H) alteration is located in exon 37 (coding exon 37) of the MYO5C gene. This alteration results from a G to C substitution at nucleotide position 4441, causing the aspartic acid (D) at amino acid position 1481 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
