The c.1027C>T (p.H343Y) alteration is located in exon 1 (coding exon 1) of the TSPYL4 gene. This alteration results from a C to T substitution at nucleotide position 1027, causing the histidine (H) at amino acid position 343 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
