Collection Method: clinical testing

The c.1560G>T (p.Q520H) alteration is located in exon 11 (coding exon 11) of the SHC4 gene. This alteration results from a G to T substitution at nucleotide position 1560, causing the glutamine (Q) at amino acid position 520 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
