Ambry Genetics

Dec 13, 2021

The c.556G>A (p.A186T) alteration is located in exon 7 (coding exon 7) of the ARHGAP44 gene. This alteration results from a G to A substitution at nucleotide position 556, causing the alanine (A) at amino acid position 186 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
