The c.277A>T (p.T93S) alteration is located in exon 4 (coding exon 3) of the CLASRP gene. This alteration results from a A to T substitution at nucleotide position 277, causing the threonine (T) at amino acid position 93 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
