The c.764C>T (p.T255I) alteration is located in exon 8 (coding exon 8) of the LRRC34 gene. This alteration results from a C to T substitution at nucleotide position 764, causing the threonine (T) at amino acid position 255 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
