The c.103C>T (p.R35C) alteration is located in exon 1 (coding exon 1) of the MYO1H gene. This alteration results from a C to T substitution at nucleotide position 103, causing the arginine (R) at amino acid position 35 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
