Collection Method: clinical testing

The c.965T>A (p.M322K) alteration is located in exon 8 (coding exon 8) of the SHC3 gene. This alteration results from a T to A substitution at nucleotide position 965, causing the methionine (M) at amino acid position 322 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
