Ambry Genetics

Nov 12, 2024

The c.1130C>G (p.T377R) alteration is located in exon 10 (coding exon 10) of the LRRC34 gene. This alteration results from a C to G substitution at nucleotide position 1130, causing the threonine (T) at amino acid position 377 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
