Ambry Genetics

Nov 12, 2021

The c.582A>T (p.Q194H) alteration is located in exon 4 (coding exon 4) of the YTHDC1 gene. This alteration results from a A to T substitution at nucleotide position 582, causing the glutamine (Q) at amino acid position 194 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
