Collection Method: clinical testing

The c.424C>T (p.H142Y) alteration is located in exon 1 (coding exon 1) of the LRRIQ4 gene. This alteration results from a C to T substitution at nucleotide position 424, causing the histidine (H) at amino acid position 142 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
