The c.440C>T (p.T147I) alteration is located in exon 5 (coding exon 5) of the MPHOSPH6 gene. This alteration results from a C to T substitution at nucleotide position 440, causing the threonine (T) at amino acid position 147 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
