Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.466G>A (p.V156I) alteration is located in exon 1 (coding exon 1) of the LRRC14B gene. This alteration results from a G to A substitution at nucleotide position 466, causing the valine (V) at amino acid position 156 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
