The c.571A>T (p.T191S) alteration is located in exon 4 (coding exon 4) of the CCDC150 gene. This alteration results from a A to T substitution at nucleotide position 571, causing the threonine (T) at amino acid position 191 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
