The c.833A>T (p.Y278F) alteration is located in exon 7 (coding exon 7) of the LIPK gene. This alteration results from a A to T substitution at nucleotide position 833, causing the tyrosine (Y) at amino acid position 278 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
