Ambry Genetics

Nov 07, 2022

The c.5701C>T (p.R1901C) alteration is located in exon 40 (coding exon 38) of the MYH4 gene. This alteration results from a C to T substitution at nucleotide position 5701, causing the arginine (R) at amino acid position 1901 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
