Collection Method: clinical testing

The c.712C>T (p.H238Y) alteration is located in exon 5 (coding exon 5) of the SUPV3L1 gene. This alteration results from a C to T substitution at nucleotide position 712, causing the histidine (H) at amino acid position 238 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
