Collection Method: clinical testing

The c.604C>T (p.H202Y) alteration is located in exon 7 (coding exon 7) of the ECHDC2 gene. This alteration results from a C to T substitution at nucleotide position 604, causing the histidine (H) at amino acid position 202 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
