Collection Method: clinical testing

The c.855T>G (p.H285Q) alteration is located in exon 5 (coding exon 5) of the SHC4 gene. This alteration results from a T to G substitution at nucleotide position 855, causing the histidine (H) at amino acid position 285 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
