Collection Method: clinical testing

The c.689C>T (p.S230F) alteration is located in exon 4 (coding exon 4) of the SHC3 gene. This alteration results from a C to T substitution at nucleotide position 689, causing the serine (S) at amino acid position 230 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
