The c.44C>T (p.T15M) alteration is located in exon 1 (coding exon 1) of the MARK1 gene. This alteration results from a C to T substitution at nucleotide position 44, causing the threonine (T) at amino acid position 15 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
